🔧 PRO TIP
The 2001 Seville runs GM's PASS-Key III+ system, not the older PASS-Key II pellet setup. The transponder is a Megamos ID 13 fixed-code chip embedded in the key head, read by an antenna ring around the ignition cylinder. The key blank is B99 (also called B102), and the cut is a standard 10-cut sidebar. If the car cranks but won't fire and you see "THEFT SYSTEM" on the DIC, the antenna ring or the chip is the problem, not the starter. Don't keep cranking. You'll just trigger the lockout timer.

2001 Cadillac Seville Transponder Key Replacement - Fast, Affordable & Professional

Got a call from a guy over in the Samarkand neighborhood in Santa Barbara. He had just walked out of his cardiologist's office, cleared to drive again, and his 2001 Cadillac Seville was sitting in the lot doing nothing. Key turned, engine cranked, but it would cough and die every time. The DIC was showing "THEFT SYSTEM" right there on the dash.

He had one key. The plastic head was cracked down the middle and wrapped in electrical tape. He told me he'd been nursing it for two years like that.

I got there and pulled the key apart on his hood. The Megamos ID 13 chip inside had shifted in the broken housing, sitting just far enough off-center that the PASS-Key III+ antenna ring around the ignition cylinder was getting a weak read. Some days it worked, some days it didn't. Today it didn't.

Cut a new B99 blank, seated a fresh ID 13 chip, and ran the key learn through the DIC using the existing key's 10-minute relearn procedure. Two learn cycles, 20 minutes of waiting while the security light blinked, then a clean start.

He just sat in the driver's seat with the engine running and didn't move for a second. Like he needed to hear it idle before he believed it.

The dealer up the road wouldn't have seen him until the next afternoon. He made it to the pharmacy with time to spare.

Cadillac Seville Mobile Service FAQ

Real costs, no dealer surprises

Do you use OEM or aftermarket transponder keys on a 2001 Cadillac Seville?
We use OEM-spec B99 key blanks with the correct Megamos ID 13 transponder chip, which is the same fixed-code chip GM used across the PASS-Key III+ platform. The chip and the cut are what matter here, not the logo on the bow. Cheap blanks with generic chips will crank the engine but trigger the theft system and leave you sitting there. We verify the transponder response against the Body Control Module before we leave. If the BCM doesn't see the right chip, the car won't run, period. We match the blank, the chip, and the sidebar cut to your specific Seville before heading out.
How long will the replacement transponder key last?
What if the new key stops working after a few weeks?
My 2001 Seville shows "THEFT SYSTEM" and won't start. Is the key bad?
Can I do the key relearn myself on a 2001 Seville without a locksmith?
