Aftermarket Replacement Parts for Car Keys

Our replacement car key parts are aftermarket components unless otherwise stated. Each individual product listing provides compatibility information to help you identify the correct part for your vehicle and key type.

Vehicle keys can vary even within the same make, model and year, so we recommend comparing your existing key carefully with the product photographs and compatibility information before ordering.

Not Sure Which Car Key Part You Need?

If you're unsure which replacement part is suitable for your key, we're happy to help. Send us clear photographs of both sides of your key via WhatsApp and we'll help identify the correct part where possible.

You can also get in touch through our Contact Us page.

DIY Car Key Repairs

Some car key parts can be replaced relatively easily, while others require the key to be opened, dismantled or soldered. Care should be taken when working on remote keys because damage to the circuit board, transponder or other internal components can prevent the remote or vehicle key from functioning correctly.

Please check the individual product description before attempting a repair and only undertake work you're confident carrying out.
