🔧 PRO TIP
The 1998 Cadillac Seville uses a transponder key, not a smart fob. No buttons, no remote, just a key that turns in the ignition. The transponder chip inside the head of that key talks to the immobilizer every time you start the car. If the chip is missing, dead, or not registered to that specific vehicle, the engine may crank and immediately die, or it may not start at all. A lot of people assume the key just needs to be cut to match the lock, and then they're confused when the car won't stay running. Cutting is only half the job. The chip has to be enrolled to the car, and that takes the right equipment connected to the OBD port. If you bought a replacement key blank online and got it cut at a hardware store, that's why it's not working.

1998 Cadillac Seville Transponder Key Replacement - Fast, Affordable & Professional

Got a call from Winter Gardens, off the east end of Lakeside. Guy inherited a 1998 Cadillac Seville from a family member and ended up with one key, badly worn, and no spare. He wasn't even sure it would last another season. Smart move to get ahead of it.

He told me he'd already called the dealer before reaching out to me. They quoted him a multi-day turnaround because they'd have to order the blank, and the labor to program it wasn't exactly friendly either. He wasn't thrilled about leaving the car at a dealership for two or three days just to get a spare key cut and programmed.

I pulled up to his place with the blank already on my van. Cut the new key to match his lock, then connected to the OBD port and ran the transponder enrollment through the vehicle security system. The Seville accepted the new key without any drama. I tested it cold, tested it again after a few minutes, and had him try it himself so he could see it working before I packed up.

Took about 45 minutes on site. He paid a fraction of what the dealer wanted, didn't lose the car for two days, and walked away with a spare that actually worked. He said the original worn key was so smooth he was worried it wouldn't even turn the cylinder anymore. We dealt with that too.

“Tim is a hero. He programmed a master proximity key for a newer Volkswagen that multiple locksmiths refused to touch. He spent hours until late at night making sure every function worked perfectly. The skill level here is incredible.”

Cadillac Seville Mobile Service FAQ

Real costs, no dealer surprises

I am locked out with no spare key. Can you come to me?
Yes. I come directly to wherever your 1998 Cadillac Seville is sitting in Lakeside or the Winter Gardens area. No tow truck, no waiting on hold with roadside assistance, no dragging the car anywhere. I carry the blanks and the equipment to handle this generation of Cadillac on site. You get a real arrival window, and I actually show up in it.
Do I need to tow my Cadillac to the dealer for a key replacement?
What do I need to prove I own the vehicle?
My 1998 Seville cranks fine but dies immediately after starting. Is that the transponder?
Can I program a replacement transponder key myself at home?
