What is a car key fob?
A car key fob is a small remote that locks and unlocks your car at the press of a button. It is the part you carry in your pocket or bag. Some fobs also start the car without a key in the ignition. A fob is different from a plain metal key, because a fob sends a coded signal that your car must recognise. The fob has a battery inside it, and the battery can be changed.
How does a key fob work?
A key fob sends a coded signal to your car when you press a button. The car checks the code, and if it matches, the doors lock or unlock. The fob and the car must be paired, which is why a new fob needs programming before it works. The old fob stops working with your car once the new fob is programmed, where your car system allows this.
Which cars use a key fob remote?
Most modern cars use a remote fob, a smart key or a flip key, and the type depends on the make, model and year. A remote fob has buttons for lock and unlock. A smart key works by proximity. A flip key folds the metal blade into the fob body. We do not list makes on this page, so call us with your car make, model and year and we will check whether we can help.
When do you need a replacement fob?
You need a replacement fob when your only fob is lost, broken or no longer works. A cracked case, dead buttons or water damage can all mean the fob cannot be fixed. A fob that works only sometimes is also a reason to replace it. If your fob still works but you want a second one, see our spare car key page instead.
What does a replacement fob cost?
The cost of a replacement fob in Birmingham depends on four factors: the type of fob, your car make and model, whether programming is needed, and whether it is a spare or your only key. We give a clear quote on the call. For the full list of cost factors, see car key replacement cost.
| Factor | How it affects the cost |
|---|---|
| Fob type | A remote fob and a smart key are different parts |
| Car make, model and year | Some cars need a different fob or more programming |
| Programming needed | A fob must be coded to your car before it works |
| Spare or only key | A spare needs a working key present |
| Fob type | What it does | Programming needed |
|---|---|---|
| Remote fob | Locks and unlocks with buttons | Yes — coded to your car |
| Smart key | Works by proximity; starts the car | Yes — coded to your car |
| Flip key | Folds the metal blade into the fob | Yes — coded to your car |
How does a replacement work?
- First, call or message us with your car make, model and year, your registration number and your location in Birmingham.
- Second, have your V5C log book and photo ID ready, because we check proof of ownership before work starts.
- Third, we come to you and supply a fob that fits your car.
- Fourth, we program the new fob to your car and test the lock, unlock and start functions with you. See car key programming for how the coding step works.
What do you need to have ready?
You need three things before we start: your V5C log book, a photo ID such as a driving licence or passport, and your car registration number. The name on the V5C and the photo ID must match. If the car is a lease car or a company car, tell us on the call, because the proof we need may differ.
How long does a replacement fob last?
A replacement fob lasts as long as it is looked after: the case, the buttons and the battery all wear with use. The battery is the part that runs out first. Water and drops shorten the life of a fob, so keep it dry.
Replacement or repair — which one do you need?
A repair suits a fob with a cracked case, a worn button or a loose part, where the electronics still work. A replacement suits a fob that is lost, water damaged or dead. We check the fob at your location and tell you which option fits before we start work. You decide — we do not start work you have not agreed to. See key fob repair for what can be fixed on the fob you have.

Frequently asked questions
How much does a car key fob replacement cost in Birmingham?

What should I do if I have lost my only car key fob?
Call 07367 634032 and tell us your car make, model and year, your registration number and your location in Birmingham. Have your V5C log book and photo ID ready, because we check proof of ownership first. We will explain what we can do for your car and give you a clear quote on the call.

No. We are a mobile service, so we come to your home, work or car park in Birmingham and program the new fob there. You do not need to tow the car or book a dealer visit. Call 07367 634032 to arrange a replacement at your location.
What proof of ownership do I need for a new key fob?
You need your V5C log book, a photo ID such as a driving licence or passport, and your car registration number. The V5C name has to be the same as the name on the photo ID. For a leased car or a company car, mention it when you call so we can tell you what else we need.
How do I know if my fob needs a repair or a replacement?
