2005 Buick Lacrosse
Mobile Key Programming Service in Ventura County

Q: What is the FCC ID for the 2005 Buick Lacrosse key?

The FCC ID is KOBGT04A. Knowing this ahead of time helps speed up the process because we can confirm we have the right blank in stock before we even leave. Call us with this number and we can give you an instant quote and get a tech headed your way.

Q: How fast can you get here?

Our average arrival time in Ventura (Lake Casitas Recreation Area area) is 15 to 25 minutes. We dispatch the closest available technician as soon as you call. No scheduling days out, no waiting for an appointment window. If you call now, we are on the way now.

Q: How long does the actual key replacement take?

Most transponder key replacements take about 15 to 30 minutes once we arrive. That includes cutting the key, programming the transponder, setting up the remote, and testing everything. From phone call to driving away, you are usually looking at under an hour total.

Q: Can I get a key made today?

Yes. Same-day service is what we do. We are available 7 days a week from 6 AM to 11:30 PM. If you call during business hours, we can usually have a technician at your location within 15 to 25 minutes. No appointment required.

🔧 PRO TIP

Early LaCrosse uses a PK3 transponder key with a separate remote, the same system as a contemporary Chevy Impala. If the theft light is flashing and the car will not start, it is usually the Passlock sensor or ignition switch module that has failed, not the key itself.

2005 Buick Lacrosse Transponder key Replacement - Fast, Affordable & Professional

Going the dealer route for a 2005 Buick Lacrosse key can take days when you factor in ordering the blank, scheduling, towing, and waiting in the queue. Buick forums are full of owners complaining about multi-day downtime just waiting for the dealer to get the right chipped key in stock. With me, the total from your phone call to a working key is usually under 90 minutes.

A working parent at the Montessori school lot in Ventura couldn't spend days on this. She had a 2005 Buick Lacrosse with a dead smart key and her child waiting after school. The dealer wanted the car for at least two days.

I showed up at the school lot. Her transponder key uses a proximity fob that talks to the BCM. I connected my IM608 to OBD and ran the security access procedure to register a new fob. Her new key, FCC ID , was learned to the car in about 30 minutes.

She pulled out with a working key at 95, child buckled in. The dealer wanted 200 plus the car for two days.

“The dealership quoted me $600 for a new Honda key. EZ Car Keyz did it for $225, same day, cut and programmed at my house. Works perfectly. Everyone should know this is an option.”

“I got locked out of my vehicle and also lost my key. Marco came out, made a new key for my Toyota, and got me back on the road. He was professional, friendly, and clearly knows what he is doing.”
