Key fobs, like the car keys themselves, can be replaced by a dealership or with aftermarket parts. It all comes down to the type of key fob you have. Some newer car models may have more complicated security features, which requires equipment purchase and programming to be done by the dealership.

How to replace transponder car key

Transponder car keys use microchips to send a signal from the key to a remote receiver in your car for security purposes, according to Great Valley Lockshop. Though these keys require programming to work, most automotive locksmiths can create an extra key for a basic transponder car key. Alternatively, a dealership can help you replace your transponder key.

Key fob with switchblade key

Like the transponder car key, switchblade keys may also be replaced by an automotive locksmith, according to Carfax. But some switchblade car keys may require programming or key cutting that can only be found at a dealership. If you’re unsure which replacement method to go with, contact your dealership or a locksmith.
