93Yes, you can replace a broken car key fob case in the UK. You have three main options: visit an auto locksmith, go to a car parts specialist like Halfords, or contact your main dealer (especially for premium brands like BMW or Mercedes).
For UK drivers with common models like the Vauxhall Corsa or Ford Fiesta, replacement key cases typically cost £15-£40 from third-party suppliers, while OEM replacements from main dealers may cost £50-£150.
Important considerations when replacing your key fob case:
- Avoid electronic interference - Keep your key fob away from mobile phones and other electronic devices, as this can cause signal issues (particularly with keyless entry systems on cars like the Nissan Qashqai or Range Rover Evoque)
- Prevent physical damage - Don't drop your key fob, especially models with sensitive electronics like Tesla's key cards or BMW's display keys
- Metal interference - Keep your key fob separate from other metal objects like coins or other keys
How to replace your key fob case:
- Carefully prise open your existing case - Use a plastic spudger (not metal) to avoid damaging the casing (particularly important for premium brand keys)
- Transfer the internal components - Take care with the circuit board and battery contacts
- Snap the new case together - Ensure all buttons align properly (test before fully assembling)
For complex UK-market key fobs (like those with flip-out blades on VW Golf keys), professional replacement is recommended to avoid damaging the transponder chip.
