Does the broken part of the key still turn in the cylinder (by using thin screwdriver to turn it)? If yes, you can still use the car by just taping the back part of the key, which contains the security chip, very close to the cylinder and then driving the car. You can then just take it to the dealer or locksmith and get the work done. Or if you want to do it for the least amount of money possible, then remove the existing key and try and get 2-3 key copies done with the portion that was broken off. If possible get one key that * doesn't *
have a chip in it . The other 'real' keys must have a chip.
- Use the chip-less key or Wrap one key's black back portion in tin foil and insert into the cylinder
- Tape the original broken key's black portion right beside the cylinder.
You can then use that key to program a new one , since it will turn and see the chip from the original key.
- Don't forget to remove the taped back part of the key when programming the new key.
