A metal key is the type of key your 1999 Chevrolet Express uses. It contains a programmed transponder chip that communicates with your vehicle theft deterrent system to authorize the engine to start. It also has 3 buttons for remote lock, unlock, and other functions. Without proper programming and GM security relearn, even a perfectly cut key will be rejected by your Chevrolet immobilizer. We program everything on site so your new key works exactly like the original.

Q: My Chevrolet says service theft deterrent system. What do I do?

That message means your Chevrolet immobilizer is not recognizing the key. Start by trying your spare key if you have one. On older Chevy models, you can try the 10-minute relearn: turn the key to ON without starting, wait 10 minutes until the security light stops blinking, turn off, then try to start. A 2014 Malibu owner described getting this message intermittently where the car refused to crank. If the relearn does not work, the issue may be a worn key, a failing ignition cylinder, or a BCM problem that needs professional diagnosis.

Q: What is the FCC ID for the 1999 Chevrolet Express key?

The FCC ID is N/A. This is the identifier printed on the back of your key fob that tells us exactly which key your vehicle requires. It ensures we match the correct blank, chip frequency, and remote protocol so the key programs correctly on the first attempt. Having this number ready when you call speeds up the process and confirms we are bringing the right key to your location.

Q: Is all-keys-lost more expensive than a regular replacement?

Yes. When you have at least one working Chevy key, adding a spare is a quick process that takes about 15 minutes on most models. When all keys are lost, the GM theft deterrent system forces a full security relearn that takes 30 minutes or more. Newer smart key systems also require at least two keys to be programmed during the AKL reset. That extra time and the second mandatory key make AKL significantly more expensive than a simple add-a-key. Get a backup key made while you still have a working one.

🔧 PRO TIP

Most Chevys from 2010 onward use the HU100 high-security sidewinder keyway. If your key looks like it has wavy cuts on the side instead of traditional teeth, that's HU100, and it requires a special cutter to duplicate.

1999 Chevrolet Express Metal Key Replacement - Fast, Affordable & Professional

A customer at the community center near Meditation Mount told me he'd already paid another locksmith full price for a 1999 Chevrolet Express key that never worked right. The engine would crank but the immobilizer cut fuel after two seconds. Classic failed key learn. The other locksmith told him the body control module was bad and left.

The module was fine. It had a locksmith problem, not a module problem. The previous tech hadn't completed GM's full key learn procedure. Chevy's immobilizer requires the key to go through a specific security learn that includes a 10-minute wait timer. If you rush it or skip the timer, the car writes the key temporarily but doesn't commit it to permanent memory.

I used my B111 Lishi to verify the blade cut was correct, then connected through OBD with my IM608. I cleared the failed key data, ran a clean learn with the full 10-minute timer, and confirmed the new key was written permanently. His transponder key, FCC ID , had the standard B111 blade and ID46 chip. I showed him the confirmation screen on my IM608 so he could see the key was fully learned this time.

He paid me 95. The dealer charges 200 for the same work. He'd already paid the first locksmith too, which I couldn't help with. But I could make sure the job was actually done right.

Mobile service FAQ

My key shell is cracking. Can you fix it without reprogramming?▼

Yes. Chevy key shells crack over time, especially around the key ring loop and the flip mechanism. You can transfer the original circuit board and transponder chip into a new shell without any reprogramming. A Colorado owner was told to buy a replacement shell on Amazon for about 10 dollars and swap the board and battery over. We can handle the shell swap and cut a fresh emergency blade if needed, all without touching the programming.
