YOSEC Gun Safe Replacement Lock Electronic Black: Best for a round black keypad match
- Round black matte metal keypad
- Keypad measures 3.74 x 3.74 x 1.14 in
- Two programmable code groups, 1–8 digits
- Requires one 9V lithium battery
A round black keypad with two programmable code groups makes this a fit to consider when the existing safe uses a similar electronic setup. YOSEC advises checking the size and having a safe technician or professional locksmith install it.
Pros
- Two programmable code groups
- Low battery warning
- 15-minute lockout after three wrong entries
Cons
- Safe compatibility depends on matching size
- Professional installation is advised
The YOSEC lock suits a safe with a round black keypad close to 3.74 x 3.74 x 1.14 in. It supports two code groups, each programmable from 1 to 8 digits, and uses one 9V lithium battery.
Three light colors indicate different lock states, and a red light after opening warns of low battery. Three wrong code entries trigger a 15-minute lockout, so check your code before repeated attempts.
YOSEC says the keypad can replace most gun safe keypads, but it also asks buyers to double-check the size. It recommends installation by a safe technician or professional locksmith.
Choose it when the existing keypad dimensions and internal lock arrangement match. If you need a step-by-step overview, read our Honeywell safe lock replacement guide for the checks involved in replacing a safe lock.
GAMES2PEOPLE Armstrong Replacement Lock for Stack-On Safes: Best for current Stack-On key locks
- Key lock for current production Stack-On cabinets
- Bright chrome coating
- Mounting hardware included
- Two keys included
This key lock is designed as a direct replacement for key locks in current production Stack-On cabinets. It does not work with cabinets that use round keys.
Pros
- Designed for current Stack-On key-lock cabinets
- Mounting hardware included
- Two keys included
Cons
- Not for round-key cabinets
- Not for dial or electronic combination locks
The GAMES2PEOPLE Armstrong is a key lock, rather than an electronic combination lock. It is designed as a direct replacement for key locks in current production Stack-On cabinets and includes mounting hardware and two keys.
Its bright chrome coating may suit a cabinet with a similar finish, but compatibility depends on the cabinet's lock style. The Armstrong does not work with cabinets that use round keys, and its description also excludes older tubular-key cabinets, smaller pistol boxes, and dial or electronic combination models.
Check the cabinet model number and current key type before choosing it. For a mechanical safe lock instead of a cabinet key lock, compare the options in our best replacement mechanical locks for safes guide.
WAHLIN PARTS Gun Safe lock Replacement Solenoid Lock: Best for a full electronic parts swap
- Electronic keypad, solenoid lock, motherboard and reset button
- Two override keys
- Programmable 3–8 digit codes
- Requires one 9V alkaline battery
WAHLIN PARTS describes this as a replacement set with keypad, solenoid lock, motherboard, reset button and two override keys. The brand says to remove the old parts and use the new set together.
Pros
- Includes two override keys
- Three programmable code slots
- Three light colors indicate lock status
Cons
- Requires an alkaline battery not included
- Brand says to replace all old parts with this set
This WAHLIN PARTS set is aimed at a buyer replacing the electronic parts together. It includes a zinc alloy keypad, solenoid lock, motherboard, reset button, manual and two override keys.
It accepts programmable 3–8 digit codes and uses one 9V alkaline battery, which is not included. The brand says to remove the old parts and use the replacement parts together, so this is not the choice for someone hoping to swap only a keypad.
The set is described for home safes, lockboxes, pistol safes, hotel safes and cabinet safes. Verify the mounting and wiring arrangement with a qualified installer before removing the old lock.
Electronic Gun Safe Lock Replacement Keypad: Best for checking a 4-pin connector
- Silver keypad and solenoid lock
- Customizable 3–8 digit PIN codes
- Upgraded 4-pin connector
- Requires alkaline batteries
The La Macaza keypad uses an upgraded 4-pin connector, which is smaller than the older 14-pin version. Confirm your safe's connector and use alkaline batteries.
Pros
- Connector type is specified
- Three-color LED status system
- Customizable 3–8 digit PIN codes
Cons
- Requires alkaline batteries
- Brand says to replace all old parts with the set
The La Macaza keypad is the option to investigate when your safe has a 4-pin connector. Its upgraded 4-pin connection is smaller than the older 14-pin version, so connector matching is central to choosing this replacement.
It uses customizable 3–8 digit PIN codes and a three-color LED status system. The brand requires alkaline batteries and says to replace all the old parts with the set.
Measure the door cutout and confirm the connector before ordering. For keypad-focused choices made for gun safes, see our best electronic keypad for gun safe roundup.
WAHLIN PARTS Gun Safe Replacement Lock Chrome Digital: Best for a chrome 14-pin keypad
- Chrome electronic keypad and solenoid lock
- 14-pin lock highlight
- Management password and up to two user passwords
- Requires one 9V alkaline battery
This WAHLIN PARTS set pairs a chrome keypad with a solenoid lock and motherboard. Its 14-pin design makes connector verification especially important before replacing an existing unit.
Pros
- 14-pin design is identified
- Three programmable password slots
- Three light colors indicate lock status
Cons
- Requires an alkaline battery not included
- Brand says to replace all old parts with this set
This WAHLIN PARTS chrome digital lock is the pick to check when your safe uses a 14-pin connection. It includes a keypad, solenoid lock, motherboard, programming reset cable and reset button.
The set supports one management password and up to two user passwords, with programmable 3–8 digit codes. It requires a 9V alkaline battery that is not included, and the brand says the old parts should all be replaced with the new set.
Confirm that your safe's connector and mounting layout match before deciding. A matching 14-pin connector alone does not confirm that the boltwork and door cutout will fit.
How can you check mounting and connector fit?
Check the existing lock before removing it, then compare its footprint, screw locations, connector and internal parts with the replacement. A keypad that looks similar can still have a different plug or mounting arrangement.
Photograph the open safe door and existing wiring, and record the keypad dimensions and connector pin count. If the lock is still working, keep it installed until you have confirmed the replacement details and have a safe technician or locksmith ready if needed.
The YOSEC unit gives keypad dimensions, while the La Macaza and WAHLIN PARTS options call attention to 4-pin and 14-pin connections. Those details help narrow the choices, but they do not confirm compatibility with every safe model.
When should you choose a keypad set or a key lock?
Choose a keypad set when your safe currently uses an electronic lock and you can confirm that the replacement matches the wiring and mechanism. Choose the Armstrong only when you have a compatible current production Stack-On cabinet with a key lock.
Do not choose by keypad color alone. Electronic sets may include a solenoid and motherboard and may require replacing those parts together, while the Armstrong is a keyed cabinet lock.
If the safe's internal parts or mounting are unclear, ask a safe technician or locksmith to identify them before ordering. For another type of compact safe, our guide to small floor safes can help you compare the safe itself and its intended installation.
What should you confirm before installing a replacement?
Confirm the safe is open and that you have access to its current lock, wiring and mounting points before starting. Follow the replacement maker's instructions, use the battery type specified, and do not force a connector or boltwork part into place.
A safe lock is part of a larger security setup, so the door and surrounding entry matter too. Our door deadbolt and reinforcement guide covers the separate checks for strengthening a room's entry.
Which safe combination lock replacement should you choose?
Choose the YOSEC if your safe matches its round keypad dimensions, the Armstrong for a compatible current Stack-On key lock, and one of the WAHLIN PARTS or La Macaza sets only after confirming its connector and complete-part requirements. The best safe combination lock replacement is the one that matches your safe's mounting, wiring and lock type before installation.

Frequently asked questions
How do I choose a replacement combination lock for a safe?
Match the lock type, mounting pattern, keypad size and connector to the parts already in your safe. Also check battery type and whether the replacement is a complete set that requires replacing the old keypad, circuit board and solenoid together.
For an electronic replacement, compare the connector before buying.
Can I replace a safe lock with a different type?
Sometimes, but the new lock must fit the door cutout and work with the safe's internal boltwork. A key lock, mechanical dial and electronic solenoid are different systems, so a similar-looking keypad alone does not confirm a fit.
Use a safe technician or locksmith if you cannot verify the mounting and mechanism.
Should I install an electronic safe lock myself?
Follow the lock maker's installation guidance and use a qualified safe technician or locksmith when advised. YOSEC specifically recommends professional installation for its keypad lock.
Incorrect wiring or a mismatched mechanism can leave the safe unable to open, so verify fit before removing the working lock.
What should I check before ordering a keypad replacement?
Measure the existing keypad and mounting area, identify the connector, and check the required battery type. A 4-pin connector and a 14-pin connector are not interchangeable based on appearance alone.
Also confirm whether the replacement set expects you to swap all old electronic parts.
