Smart Key Replacement
A smart key replacement in Birmingham gives you a new keyless key, supplied and programmed at your location. It unlocks the doors and starts the car as you approach, with no key in the ignition.

What is a smart key?
A smart key is a car key that works by proximity. You keep it in your pocket or bag, and the car senses it as you approach. The doors unlock when you touch the handle, and the car starts at the press of a button. A smart key has no metal blade to turn in the ignition. It is different from a remote fob, which needs a button press to lock or unlock.
How does a smart key work?
A smart key sends a coded signal to your car when you are close to it. The car checks the code, and if it matches, the doors unlock. The same code lets the car start when you press the start button. The key and the car must be paired first, which is why a new smart key needs programming before it works. The old key can be removed from the car system when the new key is programmed, where your car allows this.
How is a smart key different from a remote fob?
A remote fob locks and unlocks the car when you press its buttons. A smart key works without a button press, because the car senses the key nearby. Both types need programming before they work. Both are supplied as a new key at your location. A flip key is different again: its metal blade folds into the fob body. If you are unsure which type your car uses, call us with your car make, model and year and we will check. See remote fob replacement for how a button fob is replaced.
When do you need a smart key replacement?
You need a smart key replacement when your only smart key is lost, broken or no longer works. A key that is not detected by the car, or a car that will not start, can both mean the key has failed. A cracked case or worn buttons can also mean the key needs replacing. If the key still works and you want a second one, our spare car key page explains how a spare is made.
What does a smart key replacement cost?
Smart key prices are not set in advance. The cost depends on the smart key type, your car, and the programming the new key needs. No two smart keys are the same part, so each job is priced on its own details. See car key replacement cost for every factor that affects the price.
| Factor | How it affects the cost |
|---|---|
| Smart key type | Each smart key is built for a car system, so the part varies |
| Car make, model and year | A different key or extra coding on some cars |
| Programming needed | Coding pairs the new smart key to your car first |
| Spare or only key | A spare can only be made while a working key is there |
How does a smart key replacement work?
- First, ring 07367 634032 or WhatsApp us. Tell us the make, model and year, the registration number and where the car is parked.
- Second, get your V5C log book and photo ID out. We check proof of ownership before any work starts.
- Third, we come to your location with a smart key that fits your car.
- Fourth, we program the new key, then try the lock, unlock and start with you.
Our car key programming page walks through the coding step.
What should you have ready?
Have your V5C log book, a photo ID and your registration number ready before we start. The names on the V5C and the photo ID must be the same. For a lease car or a company car, the proof may be different, so mention it when you call. We check proof of ownership before any work starts, so having these ready keeps the visit smooth.
Common smart key faults
A smart key can fail in a few ways. The car may not detect the key, so the doors stay locked and the car will not start. The buttons may stop working, or the key may work only when it is very close to the car. A flat battery inside the key is a common cause. Water damage and drops can also stop a smart key working. If the key is not detected, call us and tell us what the car does when you try it.
