Pontiac GTO Key Replacement in Ventura County (2004-2006)

Here is the honest answer: yes, you can do it yourself if you already have one working key. The procedure is called the 10-minute relearn. Insert the new key, turn the ignition to ON, wait exactly 10 minutes until the horn chirps once, then turn OFF and back ON within 5 seconds. Repeat that cycle until you get three chirps and the security light stops flashing. The catch is you need the blade professionally cut first, and the timing is very precise. If you would rather not deal with it, we handle the whole thing for $175-$275 including the key. Call (805) 790-8162.

Here is the honest answer: no, you cannot. The CR2032 battery in your 2004-2006 GTO fob is welded directly to the circuit board. Trying to pry it out will destroy the fob. Your best move is to get a replacement fob, either Pontiac or Holden branded (they are identical), and have us swap your existing cut blade into the new housing and program it. Replacement fobs run about $35-$55 for the part, plus our labor to program it.

Here is the deal: one at a time only. Your GTO supports up to 10 programmed keys, which is generous, but each one requires its own full programming cycle. That means three 10-minute waits per key. If you need three keys programmed, that is about 90 minutes of ignition cycling. Each fob also has to be brand new and never programmed to another vehicle. We can knock out multiple keys in one visit if you are in Thousand Oaks or anywhere else in Ventura County.

Here is the honest answer: it is probably not the fob. First, check if the security light in your dash stopped flashing after programming. If it is still flashing, the key was not fully programmed and you need to redo the procedure. If the light is off and the car starts fine but the buttons do nothing, the likely culprit is the BCM wiring harness under your glove box. There is a known issue where the harness rubs against a metal bracket and wears through the wires. That kills keyless entry while leaving the ignition function untouched. We can inspect the harness and diagnose it on-site. Call us at (805) 790-8162 if you are in Camarillo, Moorpark, or anywhere in Ventura County.
