2004 Buick Lesabre
Same-Day Key Replacement in Ventura County

Q: What is the FCC ID for the 2004 Buick Lesabre key?

The FCC ID is KOBLEAR1XT. This is the federal registration number for your key's wireless transmitter, printed on the back of the fob. We use this to verify we are programming the exact right key for your vehicle. Getting this wrong means the remote will not work, so we always double check.

Q: Are you licensed and insured?

Yes. EZ Car Keyz is licensed by the California Bureau of Security and Investigative Services (BSIS), fully insured, and bonded. We are also NASTF Vehicle Security Professional certified, which means we have passed federal background checks and have authorized access to vehicle security data. On top of that, we are BBB A+ rated and enrolled in Google's Guaranteed program. You can verify all of this online.

Q: How do I know you are not a scam locksmith?

Fair question. The locksmith industry has a real problem with scam operators. Here is how to verify us. Look up EZ Car Keyz on Google and read our 1,000+ reviews. Check our YouTube channel with over 113,000 subscribers where we show our actual work. Verify our BSIS license number LCO 6792 on the California state website. We also give you a firm price before we come out and never change it when we arrive. If any locksmith gives you a vague price or refuses to provide a license number, hang up.

Q: Will the replacement key work exactly like the original?

Yes. We program all functions including the transponder chip, remote lock and unlock, and any other features your key has. We use professional equipment and OEM-spec key blanks. Before we leave, we test the key with you. The car starts, the remote works, everything functions exactly like your original key. If anything is off, we fix it on the spot.

🔧 PRO TIP

All Buick smart key fobs use a CR2032 battery, same as their Chevy and GMC siblings. When the battery dies, slide the mechanical key out of the fob and use the driver's door lock cylinder, then place the fob in the key pocket (usually under the armrest or in the cupholder) and press the start button.

2004 Buick Lesabre Transponder key Replacement - Fast, Affordable & Professional

His catering supplies were sitting in the back of his 2004 Buick Lesabre at the farmers market in Oxnard. It was Saturday morning, his stock was loaded, and push-to-start wouldn't respond. The car was dead and his inventory was stuck inside.

He called around and nobody could do a Buick that morning. Then he called me and I was 20 minutes out.

I plugged my IM608 into OBD and ran the BCM security diagnostics. His smart fob had lost sync after a dead car battery earlier that week. I re-registered his existing fob and programmed a spare. His key, FCC ID , was a -button remote that came back online after the security access completed.

From his phone call to engine running was about 50 minutes at 125. The dealer that finally called him back Monday wanted 300 and the car for two days. His food was fine and his Saturday market happened.

“Super fast service. About 20 minutes from the call he was already there. He had an authentic replacement on hand and made a spare key for my 2017 Nissan Rogue in about 15 minutes. Great prices, friendly, and very professional.”

“Tim went above and beyond. I struggled all day trying to program a new FOB and nothing worked. Tim helped me patiently, even recommending cheaper options since I was on a tight budget. He eventually came all the way to Ojai late at night and fixed everything.”

“My key fob stopped working while I was at Oxnard Harbor and I thought I was going to need a tow. EZ Car Keyz showed up fast, programmed a new fob, checked everything carefully, and made sure the car was fully functional before leaving.”
