1999 Cadillac Seville Transponder Key Replacement - Fast, Affordable & Professional
Cadillac uses GM's immobilizer platform, which means your 1999 Cadillac Seville has a transponder chip that communicates with the body control module every time you start the car. On older models it's an ID46 chip in the PK3+ system. On newer ones it's an ID49 with heavier encryption. The concept is the same. The car challenges the chip, the chip responds with a code, and the engine fires only if the codes match. That's why a hardware store blade copy turns the lock but won't start the engine.
A customer at Sam's Club in Lemon Grove thought only the dealer could handle that security handshake on her 1999 Cadillac Seville. The dealer quoted $326 and she assumed that was her only option because of the "computer programming" involved in Cadillac keys. Her neighbor had used me before and passed along my number.
I brought my Smart Pro to her car in the lot and connected through OBD. Her Seville uses a smart key, FCC ID , with a transponder chip that my tool programs the same way the dealer's does.
Her spare was cut, programmed, and tested in under 30 minutes. Total was around $144. The technology is real, but the Cadillac markup on programming that technology isn't justified when a mobile locksmith carries the same tools.
