Key Replacement - Save vs Dealer in Ventura County

1998 Chevrolet Cavalier MECHANICAL-KEY Replacement - Fast, Affordable & Professional

Got a call from someone over in the Village at Moorpark. She had a 1998 Cavalier, two-door, and her last key had snapped off right at the bow while she was turning the ignition. Half the key was still stuck in the lock cylinder.

She had already called the dealer. They told her she would need to tow it in, and they could get to it maybe by the end of the week. She did not like that answer.

I pulled up, checked the VIN, confirmed the B102 keyway. First thing was extracting the broken piece from the cylinder. It came out clean, no damage to the wafers. I decoded the lock on site, cut a fresh B102 blank in the van, and test-fitted it in the ignition, driver door, and trunk.

Here is the part people do not expect with these older Cavaliers: the key has no chip. Once the cut is right, it just works. But I still had to cycle the ignition and let the Passlock sensor do its ten-minute relearn because the break had interrupted the resistive signal mid-start. She sat on her front steps scrolling her phone while the security light blinked its countdown.

Handed her two fresh keys. The whole job, extraction through final test, was about 25 minutes including that relearn wait. She was back on the road same day, no tow truck, no week-long dealer hold.
