Why Replace a Car Key Case?
Over time, car key cases can become worn, cracked, or completely broken. This not only makes your key look old, but it can also:
- Expose the internal electronics to moisture and dust
- Make the key uncomfortable or unsafe to use
- Increase the risk of losing the transponder chip or buttons becoming unresponsive
- Lead to the key snapping inside the ignition or door lock
Replacing the case keeps your key working properly and helps avoid costly breakdowns or lockouts.
The Dangers of DIY Car Key Case Replacement
Many drivers try to replace their key cases after buying a cheap shell online — but here’s what often goes wrong:
- Lost transponder chips – Without the chip, your car won’t start
- Damaged circuit boards – Electronics can be easily cracked during removal
- Poor-quality cases – Cheap plastic can split within weeks, letting dirt and water inside
- Misaligned buttons – Making the remote functions unreliable or completely dead
A simple mistake can leave you stranded and turn a quick fix into a £300+ replacement.
