When you need this service
Car keys can fail in several ways that require professional intervention:
- Key snapped in the ignition barrel – The blade breaks off when turning, leaving part stuck inside.
- Broken key in door or boot lock – Extraction required before the lock can be used again.
- Cracked or splitting key blade – Metal fatigue or physical damage weakens the key.
- Damaged remote fob casing – Buttons missing, circuit board exposed, or shell cracked.
- Transponder chip loose or rattling – The chip inside the key head has become dislodged or damaged.
If the broken piece is visible and accessible, do not attempt to force it deeper with tools or glue. This can damage the lock wafers or ignition barrel, turning a simple extraction into a more complex repair.
How the service works
- Assessment – The technician examines where the key has broken and whether the remaining piece can be safely extracted without damaging the lock or ignition.
- Extraction – Specialised tools remove the snapped fragment from the lock cylinder or ignition barrel using non-destructive methods wherever possible.
- Key decoding – If the broken key is intact enough, it can be decoded to cut an exact replacement. If not, the vehicle lock may need to be decoded.
- Cutting and testing – A new key blade is cut to fit the locks and ignition precisely.
- Programming – For vehicles with transponder immobilisers, the new key is programmed to start the engine. Remote central locking functions are synced where applicable.
- Verification – The new key is tested in all locks and the ignition before the job is completed.
What affects the job
Several variables determine how quickly a broken key situation can be resolved:
- Break location – A key snapped flush inside an ignition barrel requires different extraction techniques than one protruding from a door lock.
- Vehicle make and model – Some ignitions and locks are more complex or secure than others, affecting extraction difficulty.
- Key type – Standard metal keys, transponder keys, remote flip keys, and smart keys each present different challenges when broken.
- Immobiliser system – Programming requirements vary by manufacturer and year; some vehicles need diagnostic equipment to pair a new key.
- Parts availability – If the broken key is a complex remote or proximity key, replacement shells or blades must be compatible with your specific vehicle.
- Lock condition – A worn or corroded lock may have contributed to the breakage and could need attention to prevent repeat problems.
Why use a mobile auto locksmith for broken keys
Calling a mobile auto locksmith can often avoid the inconvenience of vehicle recovery:
- On-site extraction – No need to tow the car to a workshop; the technician comes to your location in Stevenage or nearby.
- Immediate cutting – Replacement keys are cut from mobile equipment while you wait, rather than ordering from a distant supplier.
- Programming capability – Transponder and remote keys can often be programmed on the spot, depending on the vehicle security system.
- Cost transparency – You receive a quote for the specific work required before it proceeds, with no hidden dealer recovery fees.
Note that not all broken keys can be extracted or all vehicles can be programmed on the roadside. The technician will advise if your particular case requires workshop equipment or dealer intervention.

FAQs about broken car keys
Can you remove a key that has snapped off in the ignition?
Usually, yes. Auto locksmiths carry specialised extraction tools designed to hook onto the broken fragment and pull it out without damaging the ignition barrel. However, if the break is particularly deep or the ignition is already damaged, the lock may need to be removed for workshop repair.
My key is cracked but hasn’t snapped yet. Can you fix it?
A cracked metal blade should be replaced rather than repaired, as metal fatigue means it will likely break soon. The technician can cut a new key from the existing pattern before the old one fails completely, saving you from a potential lockout.
Do I need to go to the main dealer for a replacement key?
Not necessarily. Mobile auto locksmiths can often cut and program replacement keys for most makes and models without dealer involvement. This can be more convenient than arranging recovery to a dealership and waiting for appointments. However, some very new or high-security vehicles may require dealer-level diagnostics that are only available at franchised workshops.
Will the new key start my car immediately?
For vehicles with basic metal keys, yes. For those with transponder immobilisers, the new key must be programmed to the vehicle’s ECU before the engine will turn over. This is done on-site where the vehicle system allows.
What if the remote buttons are broken but the key still starts the car?
If the blade and transponder are intact, you may only need a new remote shell or button pad rather than a complete key. The technician can transfer the existing circuit board and chip into a new casing if the components are still functional.
