Common digital lock faults we repair in Singapore
From our own job records (1,000+ installs and repairs analysed), about 4 in 10 repair call-outs are a lock that won't auto-lock, about 1 in 4 are a card, tag or keypad not reading, and nearly 1 in 5 are alignment problems. For each one: what usually causes it, what we do, and whether it's usually worth repairing. Repair cost depends on the fault and the parts, so send us a photo or short video first.
1. Won't auto-lock, won't lock or won't unlock
Usual causes
- A worn or failed mortise (the lock body inside the door)
- The door and strike plate out of alignment
- A mainboard failure (less common, but possible)
What we do
We check the alignment first, because realigning fixes many of these. If the mortise has failed and parts are still available, we fit a new mortise.
Repair or replace?
Usually repairableIf it's the mainboard, we usually don't recommend repairing it. A new mainboard is expensive, so a new lock is usually better value.
2. Card, keypad or fingerprint not responding
Usual causes
- A failed card reader, keypad panel or fingerprint module
- Low batteries (try fresh batteries first)
What we do
We try to repair it or swap the faulty module when parts are available.
Repair or replace?
Repair if parts existIf the model is discontinued and parts can't be found, we'll recommend replacing the lock.
3. Door misaligned or latch not catching
Usual causes
- Sagging hinges or a door that has shifted
- A strike plate that has moved out of position
- Years of the door being slammed shut
What we do
We realign the lock and strike plate so the bolt moves freely again.
Repair or replace?
Usually repairableAlignment problems rarely need a new lock.
4. Battery leak, broken handle or dead display
Usual causes
- Old batteries leaking and corroding the mainboard
- Worn parts inside the handle
- A failed display module
What we do
We replace the handle or display module when spare parts are available. For mainboard damage from a battery leak, we usually don't recommend a repair.
Repair or replace?
Depends on partsTo prevent it: change batteries on schedule, use good alkaline batteries, and don't wait for them to run flat.
Should you repair or replace your digital lock?
These are the rules we actually use. We only recommend replacing when a repair doesn't make sense.
| Situation | Our advice |
|---|---|
| One fault, and spare parts are available | Repair |
| Door out of alignment or latch not catching | Repair (realign) |
| Parts discontinued or not available | Replace |
| Repair would cost about 60% or more of a new lock | We recommend replacing |
| Several parts have failed | Replace |
| A second fault within a year | Replace |
| Mainboard failure (including battery-leak damage) | Usually replace |
If you do replace: we suggest a lock as close as possible to your current one, or a better one if you'd like to upgrade. Every Interlock Mercury lock can replace an old Samsung or Gateman mortise lock, and its body covers the old cut-out, so there's no patching.
Repairs are quoted case by case, based on the fault and the parts needed, after we see a photo.
Repair questions
How much does a digital lock repair cost?
It depends on the fault and the parts needed, so there's no fixed price. Send a photo or short video of the lock on WhatsApp. We'll tell you whether it's worth repairing, then quote.
Why won't my digital lock auto-lock?
Most often the door and strike plate are out of alignment, or the mortise is worn. Realigning usually fixes it. If the mortise has failed and parts are available, we fit a new one.
Can a lock damaged by leaking batteries be repaired?
Leaking batteries usually corrode the mainboard. We generally don't recommend replacing a mainboard, because it's expensive. A new lock is usually better value.
Will a new lock fit the hole left by my old one?
Yes. Every Interlock Mercury lock can replace an old Samsung or Gateman mortise lock. We drill new holes, but the Mercury body covers the old cut-out completely, so there's no patching.
When should I replace instead of repair?
We recommend replacing when parts are discontinued, when a repair would cost about 60% or more of a new lock, when several parts have failed, or when it's the second fault within a year.
