2013 Chevrolet Spark
Key Replacement - Save vs Dealer in Ventura County

Q: How long does the key programming actually take once you show up?

If you have one working remote head key and just need a second one added, the OBD portion of the job on these small GM vehicles is typically around 15 minutes once I am connected. All-keys-lost takes longer because the security system runs a mandatory relearn cycle that cannot be skipped or rushed. Figure 30 to 45 minutes total for that scenario. Either way, the job happens at your car, in your driveway or parking spot, without a tow.

Q: Can you get me a replacement key faster than the dealer?

Almost always, yes. The dealer process for the Spark involves scheduling an appointment, and if they need to order the remote head key unit, you may be waiting days for parts to arrive before they even start the job. Owners on GM forums have mentioned waiting over a week just to get a second key made through a dealership. I carry the key blanks and the equipment in the van.

Q: I bought a replacement remote head key online for my 2013 Spark. Can I program it myself?

Not on the 2013 Spark. There is no DIY button sequence or ignition-cycling trick that works for this vehicle's remote head key. Enrolling a new key requires OBD-connected diagnostic equipment. The transponder portion of the key has to be registered to the immobilizer through a tool, not a dance with the ignition switch. If you bought a key online, you still need someone with the right equipment to pair it.

Q: My Spark starts fine but the remote buttons stopped working. Is the whole fob dead?

Not necessarily. On the 2013 Spark remote head key, the ignition and the remote functions are separate concerns. A dead CR2032 kills the buttons but the blade still turns the ignition. Start there. Pop the housing, check the battery, check that the contacts are clean and making solid contact with the battery face.

2013 Chevrolet Spark Remote Head Key Replacement - Fast, Affordable & Professional

I got a call from a guy out in the Corriganville area of Simi Valley, parked at a small commercial lot near one of the production facilities out there.

He'd gone to start his 2013 Spark on his lunch break and the fob was doing nothing. No lock, no unlock, not even a click. He had the key part of the remote head key working, so he could at least get in and start the car manually, but the remote functions were dead and he was convinced he needed a whole new unit.

He sounded like he'd already been down a mental rabbit hole about dealer appointments and tow trucks.

I asked him when he last changed the battery. Long pause. "I've had the car four years," he said.

I was already heading to Simi Valley for another job, so I swung by after. He was standing next to this little blue Spark looking like the car had personally offended him.

I opened the remote housing right there on the hood of my van. The CR2032 inside wasn't just dead, it had a faint greenish tinge on one edge where moisture had crept in at some point. The contact on that side was slightly corroded. I cleaned it, seated a fresh CR2032, snapped the housing back together, and handed it to him.

He pressed lock. The car beeped. He pressed it again. Beeped again. He laughed a little, like he wasn't sure whether to be relieved or embarrassed.

He didn't need a new fob. He didn't need programming. He needed a battery and about eight minutes of someone's time. The dealer would have had him schedule an appointment, bring the car in, and wait while they ran diagnostics on something a fresh CR2032 fixed.

He asked if I could make him a spare while I was there. I did. Now he's got a backup in the console and isn't one bad battery away from a problem again.

Chevrolet Spark Mobile Service FAQ

Real costs, no dealer surprises

What if I need a key for my Spark after hours or on the weekend?▼

Call us. Chevy dealer service departments close evenings and on Sundays, and key work for the 2013 Spark is not something OnStar handles. OnStar can assist with a lockout or arrange a tow, but it cannot program a replacement remote head key or run a security relearn. That means if you lose your key on a Saturday afternoon, you are waiting until Monday at minimum and then still scheduling an appointment.
