2001 Buick Lesabre Transponder Key Replacement - Fast, Affordable & Professional
When a 2001 Buick Lesabre key is done wrong, it doesn't just "kind of work." It fails. Buick's theft-deterrent system is particular about chip types. On older PK3 models, a wrong transponder triggers a solid security light and the PCM cuts fuel. On newer smart key models, a cheap aftermarket fob might lock and unlock fine but force you to use the backup pocket every time you start.
A set designer at the warehouse district in Chula Vista had a key made by another locksmith for his Lesabre that stopped working after about five days. It would start cold, but after driving and shutting off, the next start would fail with a security light. Classic symptom of a transponder that passed the initial learn but fails the deeper verification.
I used my IM608 to read the existing key data, confirmed it was the wrong chip variant, and programmed a new key with the correct transponder. His remote, FCC ID , also had a weak CR2032 battery contributing to intermittent remote failures on top of the chip issue.
The replacement has been working for months and cost him $125. The dealer would have charged $300. On Buick, the chip type matters more than most people realize because the BCM is less forgiving of close matches.

“This is the only locksmith anyone should ever call. I am still shocked at how fast he arrived and the price was hundreds less than other quotes I received. Honest, professional, and extremely efficient.”
“Locked out on a weekend night and everyone else wanted $300+. EZ Car Keyz sent Roman late at night for much less. He worked for over an hour and did not give up until the door opened. They even made a new key on the spot.”
