Every week we’re sent emails, and answer questions from our local customers in Lincoln. They ask us this simple question. Can you fix my broken car key?

This is a fair question, but it’s not a simple answer. 

Should you take your only key apart, and try and put it into a new case? Will you be able to save money instead of buying a new key?

We understand.

Some car keys can be fixed easily. Others require the calm hands of a brain surgeon, armed with the full list of instructions. Even though you want to make things better, imagine if you made things worse?

We think you should be able to. It’s hardly your fault that manufacturers have messed up with cheap design. But it depends on the make of car you have.

So here’s our guide to which keys to avoid and when we’d encourage you to have a go.

Where Can I get my car key blade cut?

This can be tricky. If you read the Amazon reviews of many keys cases sold online, the negative feedback is often that no-one will cut the key blade, which is frustrating. We recommend a good Auto-Locksmith. If they have a shop like we have, then expect to pay at least £10 , which covers wear and tear to the machine and cutter blade.
