When You Need Help With Car Locks Or Ignition Problems
Car lock and ignition faults often show up suddenly and always at the worst moment. Common scenarios include:
- Car key won’t turn in the ignition
- Key stuck in ignition or snapped in the barrel
- Steering lock won’t release
- Car won’t start; key symbol on dash
- Central locking not working on one or more doors
- Remote fob buttons work but the door won’t open
- Driver’s door lock spins or won’t engage
- Boot or tailgate won’t unlock
- Key fob not responding or intermittent
- Ignition switch failure after battery change or jump start
If you’re experiencing any of the above, it’s likely related to the vehicle’s lock hardware, ignition barrel/switch, or immobiliser system. Our mobile auto locksmiths can assess on-site and carry out the right repair, from broken ignition key extraction to full ignition repair and replacement.
How We Fix Car Lock And Ignition Faults
We follow a clear, efficient process to get you back on the road with minimal disruption:
- Initial diagnosis
- We listen to the symptoms and run on-vehicle checks. Using OBD2 diagnostics, we scan for immobiliser faults, steering lock errors, and key recognition problems.
- We assess mechanical issues in the door lock, ignition barrel, and steering lock.
- Non-destructive entry and inspection
- If you’re locked out, we use specialist lock picks and air wedges to unlock the vehicle without damage wherever possible. In the rare cases where non-destructive entry isn’t feasible due to a severe fault, we’ll explain options and get your consent before proceeding.
- Mechanical repairs
- Ignition barrel repair or replacement when wafers are worn or jammed.
- Broken ignition key extraction and key blade replacement if needed.
- Door lock repair or replacement for worn tumblers, seized cylinders, or actuator issues.
- Steering lock repair where electronic or mechanical faults prevent release.
- Electronic and programming work
- Key fob repair, key fob replacement, and transponder key programming using dealer-level tools.
- ECU/immobiliser programming and synchronisation where the car won’t recognise the key.
- EEPROM key programming for specific models that require advanced procedures.
- Central locking and remote central locking repair, including actuator diagnosis.
- New or repaired keys
- If your key is damaged or no longer communicating, we can cut a new key on-site and carry out remote key programming or smart key programming so it works with your car’s immobiliser and central locking.
- Final testing and handover
- We test the ignition turning, engine start, door locks, central locking, and remote functions.
- You drive away with a working ignition/lock system and clear guidance on prevention and maintenance.

Common Car Lock And Ignition Problems We Solve
-
Car key won’t turn Often caused by worn tumblers in the ignition barrel or a miscut/worn key. We can refurbish or replace the barrel and cut a precise key to match.
-
Key stuck in ignition We perform careful broken ignition key extraction and inspect the barrel. If a component has failed, we replace and code as needed.
-
Central locking not working on one door Usually a failed actuator or linkage issue. We test, repair or replace the actuator, and re-sync with the central locking system.
-
Remote works but door won’t open This points to a mechanical fault in the lock or linkage. We open the door non-destructively, repair the mechanism, and verify operation.
-
Steering lock won’t release On certain makes (e.g., Mercedes, VW, BMW), electronic steering lock faults can immobilise the vehicle. We diagnose via OBD2 and repair or replace the faulty unit, then perform immobiliser programming.
-
Car won’t start; key symbol on dash Suspect transponder mismatch, antenna ring failure, or immobiliser desynchronisation. We test the transponder, antenna, and immobiliser, then reprogram keys or the ECU/immobiliser as required.

FAQs About Car Lock And Ignition Issues
What should I do when my car key breaks in the ignition?
Stay calm and do not force the remaining piece. Forcing it can damage the barrel. Call us for broken ignition key extraction; we’ll remove the fragment safely and assess whether the key blade or barrel needs repair or replacement. If needed, we can cut a new key and carry out immediate transponder and remote programming on-site.
My car key won’t turn—could it be the steering lock?
Yes. A jammed steering lock or worn ignition barrel is common. First, try gently wiggling the steering wheel left and right while turning the key—don’t force it. If it still won’t turn, we can diagnose whether it’s a mechanical issue (wafers/tumblers), the steering lock, or an immobiliser problem and carry out the appropriate ignition repair.
The car shows a key symbol on the dash and won’t start. What does that mean?
This usually indicates an immobiliser or transponder communication issue. We’ll test the key’s chip, the antenna ring, and immobiliser module using OBD2 diagnostics. Where necessary we perform ECU/immobiliser programming or EEPROM key programming to restore communication.
Central locking isn’t working on one door. Is it the actuator?
Often, yes. A failing door actuator prevents locking/unlocking on that door. We can confirm with a quick test, replace the actuator, and ensure your remote central locking functions correctly again.
Can you repair rather than replace my ignition barrel?
In many cases, yes. If the wear or damage is moderate, we can refurbish the barrel and match it to your existing key. If the damage is extensive or components have failed, a replacement may be more cost-effective. We’ll always explain options and costs before work.
Will you damage my car while gaining entry?
We use non-destructive entry techniques wherever possible, including specialist picks and tools suited to your make and model. In rare cases where a component has failed and non-destructive entry isn’t possible, we’ll explain why and get your permission before proceeding.
Do you cover my area outside Guildford?
Yes. We cover the GU postcode region including Merrow, Burpham, Stoughton, Park Barn, Worplesdon, Woking, Godalming, Farnham, Cranleigh, and many more localities. See the areas we cover across GU postcodes.
How long will it take to fix an ignition or lock fault?
It depends on the issue and the vehicle. Many problems are solved at the roadside within a single visit. If a specific part is required, we’ll aim to source it quickly and return promptly. We focus on efficient, mobile service rather than fixed ETAs.
