Chip Key Replacement Steps

A chip key (transponder key) is programmed with a digital code. This type of key deflects the theft of a vehicle since only the originally-issued key will work in a vehicle's ignition. Replacing a car key will either require having a duplicate of the original key made or having an entirely new key made and programmed.


An automotive technician or a dealership owner may be able to furnish you with a duplicate copy. If you have one intact key in your possession, you can use it to have a copy made. You will need to provide proof of ownership of your vehicle prior to being granted permission to purchase a duplicate key.

The registration to your vehicle will prove that you are the rightful owner of your vehicle. Some places of business may only handle rekeying for specific vehicle makes and models. To ensure that you will be able to purchase a duplicate copy, seek the services that are offered at a business that deals solely with the make and model of the vehicle that you own.

Original Keys

If you do not have the current key to your vehicle, you may need to seek the services of a locksmith. A locksmith will use an impression of the key slot to aid them in preparing a replacement key. The make and model of your vehicle may influence the type of digital programming that the locksmith will need to perform.

The key will be cut with special machinery. The chip that is attached to a key will be the part of the key that will be programmed. A unique code will be assigned to the key and to your vehicle's ignition. A locksmith will program the key and ignition and then will test out the key to make sure that it starts up your vehicle.

Additional Copies

Transponder keys are more expensive than basic ignition keys. This is due to the advanced technology that is used to manufacture this type of key product. Obtaining vehicle key replacements that are purchased before a key goes missing can prevent additional inconveniences that will require you to have a duplicate key made or an original key made.

Any additional copies of a chip key should be stored in an inconspicuous area that only you have access to. You can either secure the replacement keys to a key ring or can store them loosely inside a concealed container.
