Quick 2016 Chevrolet Spark transponder key cut by EZ Car Keyz Simi Valley CA
🔧 PRO TIP
The 2016 Spark smart key (FCC ID HYQ4AA, part 13584500) uses GM's Hitag2 / ID46 security protocol through the Body Control Module, GM part number 42756938 on many Spark builds. A dying CR2032 won't always show as "dead." You'll get short unlock range first, then intermittent "No Remote Detected" messages on the DIC, then the push button won't respond at all. Swap the CR2032 before you start chasing bigger problems. The battery door on the HYQ4AA pops off the back with a coin twist, no prying needed.

2016 Chevrolet Spark Smart Key Replacement - Fast, Affordable & Professional

Got a call from a woman near the Simi Hills Golf Course area of Simi Valley. She had a working smart key for her 2016 Spark but wanted a spare before something went wrong. Smart move, honestly. Most people call me after they've already lost their only fob.

She had her VIN texted over before I even finished my previous job. Registration and ID ready when I pulled up. That kind of prep changes everything.

Her Spark runs the HYQ4AA five-button smart key with the Hitag2 / ID46 chip talking to the BCM. Because she had one working fob, this was an add-a-key procedure, not an all-keys-lost scenario. I used my Autel IM608 Pro to access the BCM through the OBD-II port, registered the new fob, and the system accepted it on the first pass. Cut the emergency insert blade to match, then tested every function: lock, unlock, remote start, trunk, panic, and the passive entry on both front doors.

She watched the whole thing from her driveway. When I handed her the second fob and both worked back to back, she just nodded and said "that's it?" Sixteen minutes, start to finish.

The dealer on the phone had quoted her a week wait for the part and a drop-off appointment on top of that. She got it done on site for a fraction of what they wanted, on her schedule, not theirs.

Chevrolet Spark Mobile Service FAQ

Real costs, no dealer surprises

How do I spot a fake locksmith before I get scammed on a 2016 Spark key job?
Big red flag: they won't give you a firm, single price for your specific vehicle on the phone. If they say "starting at" and can't name your key type when you give them year, make, and model, hang up. Another sign is showing up without GM-capable programming equipment and then tacking on a "programming surcharge" or invented fees like an "Automotive Key License" charge. A real automotive locksmith names the HYQ4AA, knows it's a five-button smart key with ID46 security, and gives you one price that covers the key, the cut, and the programming before they start any work.
What does "smart key" actually mean on the 2016 Chevrolet Spark?
What programming equipment do you use on the 2016 Spark smart key?
My 2016 Spark says "No Remote Detected" but the fob battery is new. What's going on?
Is the 2016 Spark vulnerable to relay theft because of the smart key?
