2011 Buick Lacrosse Remote flip key Replacement - Fast, Affordable & Professional
When a 2011 Buick Lacrosse 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 Thousand Oaks had a key made by another locksmith for his Lacrosse 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 OHT01060512, 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 185. The dealer would have charged 395. On Buick, the chip type matters more than most people realize because the BCM is less forgiving of close matches.

“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.”
“I needed a car key replacement in Hillcrest and EZ Car Keyz helped me immediately. The technician programmed a new smart key right next to my car and tested every function before leaving. Fast, friendly, and very professional.”
“About 15 minutes after calling, he was already at my home. I had lost my original Ford key and he made and programmed a new one on the spot. Very fast, very professional.”
