🔧 PRO TIP
The 2010 Cobalt uses GM's Passlock (sometimes called PK3) theft deterrent, not a traditional transponder chip in the key. The security sensor lives inside the ignition lock cylinder housing itself, reading a resistive value from the lock. The key blank is the B111/HU100 high-security sidewinder with wavy side-milling instead of standard cuts. You need a specialized cutter for that profile. If your Cobalt cranks but won't fire and the security light stays solid, that's Passlock acting up, not necessarily a key problem.

2010 Chevrolet Cobalt Transponder Key Replacement - Fast, Affordable & Professional

Got a call at 5:50 in the morning from a guy near San Jose Creek in Goleta. Warehouse worker. Shift started at six and his 2010 Cobalt key had just snapped off in the ignition. The blade broke clean where the plastic meets the metal, which happens a lot on these B111 blanks when the shell gets old and cracked. You could hear the stress. His foreman was already clocking people in.

I keep the van loaded and rolling early for exactly this kind of call. Made it to his site in about 20 minutes.

First thing was extraction. I used my B111 Lishi to pull the broken blade fragment out of the ignition cylinder, then decoded the cuts right off the wafers. No need to tow it somewhere, no waiting on a VIN-cut key from a dealer parts counter. Cut a fresh B111 sidewinder blade, transferred his existing Passlock setup, and tested the full start cycle. The security light cycled down like it should and the engine fired clean.

Hands-on time was maybe 25 minutes. I cut him a backup key too, told him to throw it in the glovebox so he's never stuck like this again.

He clocked in at 6:30. Didn't miss his shift, didn't need a tow truck, didn't burn a vacation day sitting at a Chevy dealer. He texted me that afternoon. Just said thanks. Those are the calls I like, where showing up fast actually changes somebody's day.

Chevrolet Cobalt Mobile Service FAQ

Real costs, no dealer surprises

Are you licensed and insured to work on Chevrolet vehicles in Goleta?
Yes. EZ Car Keyz is licensed through the California Bureau of Security and Investigative Services, which is the state agency that governs locksmiths. We carry full liability insurance and hold NASTF Vehicle Security Professional certification, meaning we've cleared the background checks and credentialing required to pull security data for GM vehicles. The 2010 Cobalt's Passlock system needs proper diagnostic access and the right tooling for that B111 keyway. You want someone with verified credentials handling that, not a random mobile guy with no paperwork.
How do I know you are not a scam locksmith?
Will the replacement key work exactly like my original 2010 Cobalt key?
My 2010 Cobalt security light stays on and it cranks but won't start. Is it the key?
Can I just get a regular hardware store copy of my Cobalt key?
