Car Key Fob Repair & Replacement in Birmingham

A faulty car key fob in Birmingham can usually be repaired or replaced the same day. Battery replacement costs £10–£25, fob repairs £40–£80, and a brand-new cut-and-programmed key fob £100–£250 depending on the make. We come to you and program the new fob to your car on the spot.
Key fob stopped working? Buttons unresponsive, range shrinking, or the fob's been through the washing machine? Before you pay dealer prices, talk to us — most fob problems are fixed in a single mobile visit, often for a fraction of the cost.
We repair and replace car key fobs across Birmingham: battery changes, button and case repairs, and full replacement fobs cut and programmed to your vehicle — all done at your home, workplace or roadside.
Key fob battery replacement
The most common fob fault is also the cheapest fix: a dead coin-cell battery. Symptoms are gradual — you need to stand closer and closer for the car to respond, until one day it doesn't respond at all.
We replace fob batteries for all makes (£10–£25 including the battery) and show you how to do it yourself next time. Most fobs take a CR2032 or CR2025 — but opening some fobs without the right technique breaks the clips, so be gentle.
Key fob repairs we carry out
Not every dead fob needs replacing. We repair:
- Worn or unresponsive buttons (new rubber pads and contacts)
- Cracked or broken fob cases (new shells, electronics transferred)
- Water-damaged fobs (cleaned, dried and tested — when salvageable)
- Loose battery contacts and broken solder joints
- Worn key blades (re-cut from code or the original)
Full key fob replacement & programming
If the fob is beyond repair — or lost entirely — we supply, cut and program a brand-new fob to your car. The new fob is coded to your vehicle's immobiliser using professional diagnostic equipment, and we test every button and the remote start (if fitted) before we leave.
Dealer replacement fobs typically cost £200–£400+ and take days to order. Our mobile service is usually same-day and significantly cheaper.
Key fob vs dealer: the honest comparison
Dealers order from the manufacturer — slow and expensive. We carry the most common fobs in stock and program on-site. For rare or very new models we may need to order, but we'll tell you that upfront with a clear timescale.
One thing dealers sometimes claim: that only they can program keys. Not true — licensed auto locksmiths use the same professional-grade programming equipment.
