Ignition cylinder rekeying is a specialized automotive locksmith service that changes the pin pattern inside the existing ignition cylinder to match a new key. Unlike cylinder replacement (which installs a brand new cylinder), rekeying modifies the existing cylinder by swapping the pin tumblers.
Rekey is useful in specific situations. When you lose the only key to a car, rekeying resets the ignition so the old key no longer works - more secure than just cutting a new key to the old pattern. When your ignition and door lock keys are different, rekeying the ignition makes them match for single-key operation.
And when the ignition cylinder is in good mechanical condition but you want a new key pattern, rekeying is cheaper than replacement.

How ignition cylinder rekey works
Ignition cylinder rekeying follows the same basic principle as residential lock rekeying. The cylinder contains a stack of pin tumblers that are positioned to accept a specific key cut pattern. Rekeying replaces these pin tumblers with a new stack cut to a different key pattern.
The procedure for automotive ignition cylinders is more complex than residential locks because ignition cylinders are often recessed in the dashboard or steering column. Access requires partial disassembly of trim panels, sometimes removal of the steering wheel, and always careful handling of any electronic components connected to the cylinder.
For cars with transponder immobilizers, ignition cylinder rekey also involves the transponder chip. The new key must be both mechanically cut to match the rekeyed cylinder AND programmed to the car's immobilizer. This combines mechanical and electronic procedures in one service call.
Typical ignition cylinder rekey takes 60-120 minutes depending on cylinder access. Some European luxury cars with integrated electronic ignition modules may take longer or require bench work.

Ignition cylinder rekey FAQs
Common questions about ignition cylinder rekeying.
What is ignition cylinder rekey?
Changing the pin pattern inside the existing ignition cylinder to match a new key. The existing cylinder stays in the car; only the internal pin tumblers are swapped. Results in a new key that works and old keys that don't.
How much does ignition rekey cost?
Standard rekey: $165-$245. With transponder chip programming: $225-$345. Cylinder replacement (if rekey isn't possible): $245-$545.
Rekey is about half the cost of replacement.
When should I rekey instead of replace?
Rekey when the cylinder is mechanically sound but you want a new key pattern. Replace when the cylinder is damaged, worn, or seized. We assess onsite and recommend the right approach.
Can you rekey to match my door locks?
Yes. Matching ignition and door locks is a common rekey reason. We cut a new key and rekey both the ignition and door cylinders to the same pattern, so one key works everywhere.
Does ignition rekey include transponder programming?
For vehicles with immobilizers, yes. Rekey includes both mechanical pin swap and transponder chip programming. The new key is both mechanically cut and electronically authorized.
How long does ignition rekey take?
60-90 minutes for accessible cylinders (most American brands). 90-150 minutes for European luxury brands with complex access. 150-210 minutes if steering wheel removal is needed.
Can you rekey a BMW or Mercedes ignition?
Yes. European luxury ignition rekey is within scope but takes longer due to cylinder access complexity and integrated immobilizer procedures.
What if rekeying doesn't work?
Very rare. If the cylinder is too damaged for rekey, we recommend replacement as the alternative. Replacement adds cost but always works.
Is ignition rekey as secure as replacement?
For invalidating old keys, yes - both change the key pattern. Replacement adds fresh mechanical components, which is useful if the existing cylinder is worn.
Can you rekey a modern push-to-start car?
Push-to-start cars don't have traditional ignition cylinders. 'Rekey' for push-to-start means reprogramming the immobilizer to accept a new key fob and invalidate old ones. Different procedure but accomplishes the same goal.
Do you need the old key for rekey?
Not required. We can rekey without the old key. With the old key present, the job is slightly faster because we can verify operation before and after.
Is ignition rekey covered by my car warranty?
Typically no - rekey is an owner-initiated service, not a repair for a warranty defect. Out of pocket for most owners. Insurance may cover in cases of theft recovery.
