2005 Cadillac STS Smart Key Replacement - Fast, Affordable & Professional

Lock decoding means I read your car's lock to cut a key without drilling, without damaging the cylinder, and without replacing anything. The Cadillac looks exactly the same when I leave.

A driver at a highway rest stop near Bancroft had his key go stiff and nearly snap in the ignition of his 2005 Cadillac STS. The blade was visibly worn and he could feel it catching on the wafers. He was afraid to force it one more time. Another locksmith quoted him over the phone for a full ignition cylinder replacement at over $500.

I used my HU100 Lishi to decode the lock from the door cylinder where the wafers were still clean. It reads each wafer position without touching or damaging them, which gave me the exact cut depths for a new blade. I cut a fresh key from the decode and programmed the transponder chip through OBD. His smart key, FCC ID M3N-65981403, just needed a new blade with the correct chip. The old ignition wafers were worn but not failed.

No drilling and no cylinder replacement. His total was $306. The other locksmith's plan would have been $563 or more with a new cylinder and keys. His original ignition works fine with a properly cut new blade.

Cadillac STS Mobile Service FAQ

Real costs, no dealer surprises

My key broke in the ignition. Can you get it out?
Yes. Broken key extraction is a standard job for a mobile automotive locksmith. We use specialized tools to remove the broken piece without damaging your Cadillac's ignition cylinder. Once it is out, we can cut a new key from the extracted piece or from your vehicle's lock data and program it on the spot. Older Cadillac SRX models are known for keys getting stuck due to the brake transmission shift interlock mechanism. One 2005 SRX owner showed that a stuck key can be released by bypassing the BTSI interlock under the steering column, a procedure a locksmith can do in minutes without damaging anything.
