5 Best Double Sided Keyless Locks
(Prices shift on Amazon regularly — confirm current pricing on each product page before buying.)
If you’ve got a gate, fence, or door that people need to open from both sides — a backyard gate, a side entrance, a rental property door — a regular keypad lock only solves half the problem. It codes one side and leaves the other side as an afterthought, usually a plain knob or a spot for someone to reach over and flip the latch. A double sided keyless lock puts a full keypad (or keypad plus key) on both faces of the door, so nobody’s getting in — or out — without the right code, from either direction.
We looked at the mechanical and keypad-based double sided locks that keep showing up as genuinely good options for homeowners, landlords, and anyone managing a gate that needs two-way control. Here are five worth your money, what makes each one different, and how to figure out which one actually fits your door.
5 Best Double Sided Keyless Locks Reviews One by One
( Most People Demanded Research )
Certainly, here are three of the best double-sided keyless locks that are highly sought after by most homeowners for their security and convenience:
1. JOUNJIP Mechanical Keyless Combination Latch Lock
Upgrade your security with the JOUNJIP Mechanical Keyless Combination Latch Lock, a double-sided keypad lock designed for gates, fences, and windows. With a durable satin chrome finish, this battery-free, power-free lock provides reliable access control without worrying about electrical failures or dead batteries.
(Best Double Sided Keyless Lock for Home Security)
The JOUNJIP earns the top spot because it nails the fundamentals of what people actually search for in a double sided keypad door lock: no batteries, no wiring, and dual keypads that genuinely lock both sides. It’s built specifically for gates, fences, and windows — anywhere you need real two-way code control without running power to a remote part of your property.
What makes it stand out:
- 100% mechanical operation — works during a power outage, no batteries to replace
- Dual keypads on both faces, each capable of holding its own passcode
- “Bump key proof” design — there’s no keyhole for a bump key to exploit
- Code is set from the back of the keypad and can be changed without disassembling it
- Works on both left- and right-opening doors
Who it’s for: Anyone asking “can you install a keypad lock on both sides of a door?” for a gate or fence application — this is purpose-built for exactly that.
Keep in mind: This is a latch lock, not a deadbolt, so it’s best suited to gates and secondary doors rather than a primary entry door that needs deadbolt-level security. Installation is rated intermediate-to-advanced, and passage mode (free entry/exit without a code) isn’t available on this model.
2. VEVOR Mechanical Keyless Entry Door LockÂ
Upgrade your security with the VEVOR Mechanical Keyless Entry Door Lock, designed for outdoor gates, gardens, garages, and more. This double-sided, 14-digit keypad lock delivers reliable access control without the need for batteries or power, ensuring long-lasting security in any weather.
VEVOR has built a reputation on delivering pro-level hardware at a lower price point, and this double sided electronic door lock (mechanical, despite the “electronic” naming some listings use loosely) delivers a lot of hardware for the money — a full handle set, a 14-digit keypad on each side, and genuinely weatherproof construction.
What makes it stand out:
- Zinc alloy construction with a corrosion-resistant electroplated coating — built for outdoor exposure
- 14-digit keypad allows a longer, harder-to-guess code than many competitors
- Adjustable handle sides and a push-pull latch structure for straightforward replacement of an existing lock
- Large padding plate (6.2″ x 2.5″) covers existing screw holes, so you’re not left patching your door
Who it’s for: Homeowners replacing an existing gate or garage lock who want real weather resistance without paying Lockey-level prices.
Keep in mind: Like the JOUNJIP, this is a mechanical latch-style lock best suited to gates, yards, garages, and similar secondary access points rather than a primary front-door deadbolt application.
3. BOTHSTAR Keypad Door Knob with Key
 Secure, Smart & Keyless Convenience
Upgrade your home or office security with the BOTHSTAR Keypad Door Knob, a double-sided, keyless entry lock that combines modern security features with easy installation. Designed for homes, offices, bedrooms, and garages, this heavy-duty, weatherproof lock offers a seamless blend of security and convenience—without requiring WiFi or internet access.
The BOTHSTAR is the one lock on this list that behaves more like a smart lock than a purely mechanical gate lock — it’s a keyless lock with keypad on both sides, plus a backup key cylinder on both faces, and a backlit keypad for nighttime use. That combination makes it a strong fit for doors that see regular daily traffic rather than an occasional-use gate.
What makes it stand out:
- Dual-sided keypads with identical keys on both sides for consistent access
- 50 user codes plus 1 master code, so you can track access for a family, office, or rental property
- Password synchronization option — change the code on one side and sync it to the other automatically
- Backlit keypad for entering codes in the dark
- Visitor mode and silent mode for flexible day-to-day use
Who it’s for: Anyone searching for a keypad deadbolt with interior keypad for a door that gets used constantly — home offices, bedrooms requiring two-way privacy control, or small business entries.
Keep in mind: This is battery-powered (with a backup key and USB-C emergency power port), so it’s not a fit if you want a zero-maintenance, no-batteries-ever lock — check the “no power needed” mechanical options above if that’s a priority.
4. Lockey USA M210JBDC Mechanical Keyless Deadbolt
 Reliable, Secure & Hassle-Free
The Lockey USA M210JBDC is a fully mechanical, keyless deadbolt, offering secure and convenient access without the need for batteries or power. Built for durability and ease of use, this push-button lock is perfect for homes, offices, and commercial spaces where reliable security is a must.
If the word “deadbolt” matters to you — and for a lot of double sided applications, it should — this is the pick. Lockey USA has built its entire catalog around mechanical, code-based deadbolts, and the M210 Double Combination (DC) model puts a genuine adjustable deadbolt behind vandal-resistant keypads on both sides.
What makes it stand out:
- Real adjustable deadbolt, not just a spring latch — meaningfully more resistant to forced entry than latch-only locks
- Installs in minutes on doors with an existing standard 2-1/8″ deadbolt hole, no drilling required
- Vandal-proof, rust-resistant keypad housing
- Thumbturn on both interior and exterior for quick manual operation alongside the code
- Backed by Lockey’s Lifetime Mechanical Warranty
Who it’s for: Anyone comparing options for a commercial double sided keypad lock or a security-focused residential gate/door where a full deadbolt — not just a latch — is the requirement.
Keep in mind: Because it’s designed to retrofit an existing deadbolt hole, double check your door’s current bore size and thickness (1-1/8″ to 2″, with extension kits available up to 5″) before ordering.
5. Lockey USA 2835MGDC Mechanical Keyless Lever Lock
Secure, Durable & Hassle-Free
The Lockey USA 2835MGDC is a fully mechanical, keyless push-button lever lock, designed for secure and effortless access without the need for batteries or electricity. With ADA-compliant levers, an adjustable latch, and reversible handing, this heavy-duty lock is perfect for homes, offices, and commercial spaces where reliability and security are top priorities.
The 2835MGDC is Lockey’s answer for the harshest installation conditions — its Marine Grade finish is specifically formulated to resist corrosion in coastal or high-moisture environments, which makes it one of the few genuinely good options for a security screen door, dock gate, or pool enclosure that takes a beating from the elements.
What makes it stand out:
- Marine Grade finish resists corrosion better than standard coatings — built for coastal and wet climates
- Full ADA-compliant lever handles on both sides, not just knobs
- Built-in passage mode — each side can be independently set to stay unlocked when you want free access
- 100% mechanical, zero batteries or wiring
- Reversible handing and adjustable backset (2-3/8″ or 2-3/4″) for flexible installation
Who it’s for: Anyone specifically searching for the best double cylinder smart lock for outdoor or coastal conditions where standard finishes corrode within a year or two — this is the durability-first pick on the list, and priced accordingly.
Keep in mind: This is the most expensive lock here, and that cost reflects genuine build quality rather than smart features — it has no app, no Bluetooth, and no Wi-Fi. If you want app control, see the FAQ below on smart lock connectivity.
Which Double Sided Keypad Lock Is Best?
It depends heavily on what you’re locking:
- Gates and fences: JOUNJIP or VEVOR — both are purpose-built latch locks for exactly this, no power required.
- A door people use constantly (home office, interior privacy door): BOTHSTAR — the backlit keypad and code-sync features matter more on high-traffic doors.
- Anywhere you need a true deadbolt, not just a latch: Lockey M210JBDC.
- Coastal, marine, or heavy-outdoor-exposure installs: Lockey 2835MGDC.
- Rental properties managing multiple tenants: BOTHSTAR’s 50-user-code capacity or the Lockey lever lock’s passage mode both work well — see the FAQ below for more on rental use specifically.
Frequently Asked Questions
What is a double sided keyless lock?
It’s a lock with a functioning keypad (and often a backup key) on both faces of a door, so a code is required to operate the lock from either side — unlike standard keyless locks, which typically only code the exterior and leave the interior as a simple turn-knob or lever.
Are double sided keyless locks safe?
Yes, when installed on the right type of door. They’re a strong security choice for gates, fences, sheds, and non-egress doors. They should never be installed on a door that serves as a required emergency exit, since a code requirement on the exit side can trap people during an emergency — check your local fire code before installing one on any door that might serve as an escape route.
Can you install a keypad lock on both sides of a door?
Yes — that’s exactly what a double sided (or double cylinder) keyless lock is designed for. Most of the mechanical options on this list, like the JOUNJIP and VEVOR locks, are specifically engineered with two independent keypads, one per side, and are a common upgrade for gates and fences that need two-way control.
Which double sided keypad lock is best?
For most people, a purpose-built mechanical gate lock like the JOUNJIP or VEVOR is the best starting point for outdoor gates and fences, while the BOTHSTAR suits interior/exterior doors with regular daily traffic, and the Lockey deadbolt models are the strongest choice when security is the top priority.
Do double sided smart locks require Wi-Fi?
Not necessarily. Every lock on this list is either fully mechanical (no power at all) or battery-powered without requiring Wi-Fi or an app — meaning they’ll keep working during an internet outage or power failure. If you specifically want app-based remote access or activity logs, you’d need to look at a dedicated Wi-Fi or Bluetooth smart lock, which is a different product category from the mechanical and standalone-keypad locks covered here.
Are double cylinder keypad locks legal?
Generally yes for gates, fences, and non-egress doors, but many local and state fire codes restrict or prohibit double-cylinder locking mechanisms (including double sided keyless locks) on doors that serve as a required means of egress from a building. Always check your local building and fire code before installing one on any interior door, especially in a bedroom, rental unit, or any space with occupancy requirements.
Can a double sided keyless lock be used on glass doors?
Most of the mechanical locks on this list are designed for standard wood, metal, or fiberglass doors and gates with a bored or mortised install — they’re not made for frameless or fully glass doors, which need specialized glass-door lock hardware with different mounting mechanisms. If you have a framed glass door (aluminum or vinyl frame with a glass panel), standard hardware like this can often still work; check your door’s frame material and existing hole spacing before ordering.
The Bottom Line
For most gates and fences, the JOUNJIP Mechanical Keyless Combination Latch Lock is the best double sided keyless lock you can buy — no batteries, genuine two-way code control, and a price point that makes sense for a secondary access point. If you specifically need a true deadbolt rather than a latch, step up to the Lockey M210JBDC. And if your installation is anywhere near salt air, humidity, or heavy weather exposure, the Lockey 2835MGDC‘s Marine Grade finish is worth the higher price tag.
