Fob dead or weak? We check it properly.
Car Key Battery Replacement at Your Vehicle
A fob that needs several presses, or a dashboard message saying key battery low, usually means the cell is running out. Our mobile auto locksmiths fit the correct battery, test the remote and resync it where the vehicle needs it, at your car. We cover Essex, Bristol, Cardiff and Newport, and St Helens and Merseyside.
What this service covers
Fobs use a range of coin cells and some keyless keys need careful opening to avoid damaging clips or seals. We open the shell, fit the right battery and check the buttons, range and keyless entry before we leave.
Some vehicles lose sync after a battery change. Where that happens, the remote is resynchronised to the car on the spot so locking and unlocking work as normal.
If a fresh battery does not restore normal range, that usually points to a failing remote. In that case we can supply and programme a dealer quality replacement key, backed by our two year key warranty, rather than leave you with a fob that keeps letting you down.
Included as standard
- Correct battery fitted for your fob
- Buttons, range and keyless entry tested
- Remote resynced where the vehicle needs it
