There s a special chip in the head of the transponder key that helps keep your car extra secure.
I ve lost my car key and have no spare.
The only way to bypass one of these venues is if you know someone that has the skills and equipment to carry the job out without charging you any fee.
If you have lost the transponder and you don t have spare a locksmith will have to make a key that will fit the lock get a new chip and then connect it with the transponder in the car.
The old key will be de programmed to make it useless in case it has been stolen.
No it does not matter if you ve lost your only set of keys an auto locksmith can provide you with a replacement and re program the new car key to match your vehicle.
If a key without the special chip tries to start your car the vehicle won t start.
If you have lost your car keys and you have no spare you will definitely have to deal with someone at a dealership or at a locksmith shop.
