It’s more likely that you will be allowed to utilize an aftermarket key fob if your automobile is at least ten years old, according to CR’s Ibbotson. Many of these less sophisticated fobs can be configured by the consumer, a local technician, or an automotive locksmith.
Ibbotson advises making sure to phone your neighborhood garage first to confirm that they can do the task, as key-fob programming equipment levels can vary from shop to shop.

We took our vehicle to M.J. Sullivan Hyundai in New London, Connecticut, where we were charged $120 for programming (one hour of labor), which is what they would have charged us if we had purchased the key fob from them.
Hyundai sent us a laser-cut mechanical backup key for $72.47, bringing the total cost to $272.42 (the car waited at the shop for two days); if we had ordered the key fob through the store, the total would have been $428.92).
For some makes and models, you can purchase a cheap aftermarket fob and program it yourself if your home unexpectedly gains a third driver, such as a teenager.

Although it lacks the Chrysler branding on the back, it resembles the two original fobs that came with the minivan when it was new.

Chrysler customers can program a third key fob themselves if they already have two functional ones, just like GM owners can. The owner’s manual contains clear and straightforward programming instructions.
