.Every week we answer the same question at our shop in Lincoln. Can you fix my broken car key?

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

The real question is, should you take your only working car key apart, and try and put it into a new case? Will you be able to save money instead of buying a new key? Or, will you end up without a car key that will start your car?

We understand.

Some car keys are 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?

Fix My Broken Car Key Repair Problems ( or challenges )

We recommend getting your new key case to turn your car locks before breaking open your old key. You have two choices.

  1. Get the new blade cut.
  2. Swap the blade to take your new one.

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 that no-one will cut the key blade, which is frustrating. Contact a good Auto-Locksmith. If they have a shop like we have, expect to pay at least £10 to get it cut. This charge covers wear and tear to the machine and cutter blade, plus a bit of electric to keep the lights on!


Swap the key blade over.

Either easy, or a bit of a pain. It depends on whether your old original blade will fit into the replacement case that you buy.

In general, the Vauxhall flip keys we sell on Amazon swap over with just a tiny modification to the original key blade. However both the Hyundai/Kia cases and the VW/Seat/Skoda cases need more intense work with a needle file before the old blade cab be used in the new case.

For some this is a really simple job because you’re used to using small hand tools. However, if you’re not happy about this, then it’s completely understandable, and you are better off getting the blade cut.

Fix My Broken Car Key – That’s it!

  1. Get the new case turning the locks
  2. Open the old broken key
  3. Carefully swap the electronics
  4. Fit a new battery
  5. Job Done

      Hi Stuart
      You can do this yourselda case from ebay. Your key is in twoparts, the button part and the flip part. You only have to swap the button part of the key , leave the flip part alone.
      Open the remote part, remove the board and put it into the replacement case.
      You shouldn’t need any programming etc
