Car locks are one of those things you rarely think about — until they stop working. Whether it’s a snapped key, a jammed lock, or an electronic fob that’s gone rogue, car lock issues can strike unexpectedly and leave you stranded.
In this guide, we’ll walk you through the most common car lock problems, why they happen, and how professional auto locksmiths like us fix them quickly and safely.
The problem:
One of the most frequent issues we see is a key snapping inside the lock or ignition. Over time, keys weaken due to constant use, or they bend slightly, eventually breaking off during use.
How we fix it:
We use specialised extraction tools to carefully remove the broken piece without damaging the lock.
If the key is worn or damaged, we cut and program a new one on the spot.
If necessary, we also inspect the lock or ignition to ensure there’s no internal damage.
💡 Pro tip: Avoid forcing a stiff key — it’s usually a sign the lock needs servicing.
The problem:
Locks that refuse to turn or feel stiff are often caused by dirt, rust, or internal wear. In colder months, moisture inside the lock can freeze and prevent it from moving at all.
How we fix it:
We clean and lubricate the internal mechanism to restore smooth movement.
If the internal components are worn or broken, we can repair or replace them.
In severe cases, we may fit a completely new lock cylinder that’s keyed to match your existing key.
đź’ˇ Pro tip: Regularly lubricating your car locks (especially before winter) helps prevent jamming.
The problem:
If all doors stop responding to your remote or only some of them lock, it’s usually a sign of a faulty actuator, blown fuse, or an issue with the central locking module.
How we fix it:
We run a diagnostic to identify whether the issue is mechanical or electrical.
If it’s an actuator failure, we replace the faulty unit.
For electrical problems, we check wiring, fuses, and relays, repairing or replacing components as needed.
💡 Pro tip: If one door consistently fails while others work, it’s often a failing actuator.
The problem:
Losing your keys (or having them stolen) isn’t just inconvenient — it’s a security risk. Without action, anyone who finds them could access your car.
How we fix it:
We can create a brand-new key on-site using your vehicle’s lock or VIN data.
For stolen keys, we reprogram the immobiliser so old keys no longer work.
If needed, we can replace all locks for complete peace of mind.
đź’ˇ Pro tip: If you suspect theft, always contact the police and your insurer before calling a locksmith.
The problem:
Modern vehicles rely heavily on remote key fobs — but they can fail without warning. Common causes include a dead battery, signal interference, or internal circuit damage.
How we fix it:
We replace the fob battery and test the signal.
If the fob is damaged, we repair or reprogram it — or supply a replacement.
We also check for receiver issues in the vehicle itself if the fob is working but not connecting.
đź’ˇ Pro tip: Always keep a spare key fob battery in your glovebox for emergencies.
The problem:
If your key won’t turn in the ignition or gets stuck, the ignition lock cylinder could be worn out or misaligned. Forcing it can cause expensive steering column damage.
How we fix it:
We inspect and repair the ignition lock components.
If repair isn’t possible, we replace the cylinder and ensure it matches your existing key.
We also check the immobiliser system if the engine still won’t start after repair.
💡 Pro tip: If your ignition starts feeling “gritty” or sticky, get it checked before it fails completely.
While some minor issues (like changing a fob battery) can be DIY’d, most car lock problems require professional tools and expertise. Attempting to fix them yourself can lead to:
Damaged locks or ignition systems
Increased repair costs
Voided insurance or warranty coverage
