🔧 PRO TIP
The 2003 Chevrolet Express does not use a transponder chip. It runs GM's Passlock II system, which reads a resistor embedded in the lock cylinder itself, not the key. The key is a standard B102/B106 mechanical cut with no electronics inside. If your Express cranks but won't fire and the "SECURITY" or theft light stays solid on the dash, the problem is the Passlock sensor in the cylinder, not the key. Replacing the key alone won't fix that.

2003 Chevrolet Express MECHANICAL-KEY Replacement - Fast, Affordable & Professional

Got a call from a guy out near Wildwood Mesa Trail in Thousand Oaks. His 2003 Chevrolet Express cargo van, the one he uses for weekend trail support runs, had a snapped key stuck in the driver's door.

He tried pulling the broken piece with needle-nose pliers and just pushed it deeper. By the time he called me, he had already spent an hour on it.

I extracted the broken bit from the lock cylinder, then decoded the wafers in the door to get the original cut pattern. His van uses the GM B102 keyway, nothing high-security, no sidewinder, no chip inside the key. Just a plain brass mechanical key that talks to the Passlock II sensor built into the ignition lock cylinder housing. The key doesn't carry any signal. It just turns the cylinder, and the Hall-effect sensor inside reads the magnet on the lock cylinder rack to verify the resistance value.

Cut two fresh B102 blanks on site. Tested both in the driver door, passenger door, and ignition. Smooth turns, no binding. Started the van three times with each key. No security light, no ten-minute lockout, no crank-no-start.

He kept rotating the broken key in his fingers while I worked, like he was trying to figure out where it gave up. I told him brass gets tired after twenty years. He laughed and pocketed both new keys.

The whole job took about twenty minutes. A dealer would have wanted the van towed in and days on the schedule.

“They responded instantly, showed up within an hour, and arrived exactly when they said they would. Made a copy and programmed a fob for my 2014 car with a worn ignition in about 15 minutes. The new key works perfectly and feels like a dealer key.”

Chevrolet Express Mobile Service FAQ

Real costs, no dealer surprises

I lost all my keys for my 2003 Chevrolet Express. Can you still make a new one?
Yep. Since the 2003 Express uses a mechanical key with no transponder, all-keys-lost is actually simpler on this van than on most modern vehicles. I decode the lock cylinder wafers on site to get your original key cuts, then cut a fresh B102 blank to match. No programming, no security relearn timer, no diagnostic port work. The Passlock II system lives in the ignition cylinder, not the key, so once the new key turns the cylinder correctly, the van starts. The whole process runs about 15 to 25 minutes depending on lock condition.
Do I need to tow my Express to the dealer if I have no keys?
How long does it take to replace a key for the 2003 Chevrolet Express?
My Express cranks but won't start and the security light stays on. Is it the key?
Can I just get a copy of my Express key at a hardware store?
