The Chevrolet Trax has one of the cleaner two-era splits we deal with, and also one of the easiest to get wrong if you order online. The original Trax and the redesigned Trax share a name and almost nothing under the key, so a fob bought by model name is a coin flip unless the generation is confirmed. As a budget crossover popular with younger Statesboro drivers, the Trax mostly brings us spares and lockouts, but the wrong-generation fob is a steady second category.
We are a mobile automotive locksmith and come to wherever the car is, whether that is a space at the Statesboro Crossing, a student lot near Georgia Southern University, or a driveway off Northside Drive. Before we head out we confirm the generation by VIN, so a redesigned Trax never gets a part built for the original car or the other way around.
Trax Generations and What Each One Uses
The 2015-2022 Trax uses an HU100 blade with an ID46 chip, carried by a flip remote, the OHT01060512. It is a turn-key car: the blade flips out, the chip has to be read for the engine to start, and the remote handles the doors. A blank with an unprogrammed chip will turn but never crank.
The redesigned 2024-2025 Trax jumped to proximity push-to-start on the B119 emergency blade with the HYQ4ES fob. The blade is now an emergency opener rather than something you turn. The gap between the generations and the complete platform change is exactly what trips up online buyers, so matching your specific generation is the single most important step before any part is ordered.
Chevrolet Trax Keys and Fobs by Generation
The Trax uses two very different key systems depending on generation: a remote flip key on the earlier cars and a proximity push-to-start fob on the redesign. The shape of the key and whether the car has a start button are the quickest tells, and we confirm the exact part by VIN before we head out.

Proximity Fob Service for the Trax
Push-to-start on the Trax arrived with the 2024-2025 redesign, which uses the HYQ4ES proximity fob. With the fob in your pocket the doors unlock on touch and the car starts with the button. The 2015-2022 cars are turn-key flip keys, so the first thing we confirm is whether your car is the proximity generation. On the redesign, adding or replacing a fob is a programming job, and we verify lock, unlock, and push-button start before we leave.
Telling a Dead Trax Fob Battery From a Programming Issue
Before assuming the worst, rule out a weak battery. Trax remotes and proximity fobs run on a CR2032 coin cell, and a tired one is the most common reason a flip key stops locking from a distance or a redesigned Trax makes you hold the fob to the start button. A fresh cell often brings it right back.
A real programming fault is different. On a 2015-2022 car, if the remote works but the key turns and the engine will not start, the ID46 chip may not be reading. On a 2024-2025 car, if a new battery does not help and the dash reports the key is not detected, the fob needs to be re-paired. Either way that is a programming job, not a battery swap.
When the Trax Ignition or Locks Act Up
On the 2015-2022 flip-key Trax there is a real ignition cylinder that can wear over years of use. The symptom is an HU100 key that sticks, has to be wiggled, or will not turn even though the ID46 chip is fine. That is a mechanical repair rather than a programming one, so we diagnose it at the car; sometimes a fresh blade cut to the original code restores smooth operation, other times the cylinder needs service. The redesigned car is push-to-start and has no comparable cylinder.
All-Keys-Lost on the Chevrolet Trax
Losing every working key to a Trax is a bigger job than copying a spare, but one we handle on-site. With no key to act as an authentication seed, the programmer reads the immobilizer data from the car before it can enroll a new key, which on the redesigned proximity car means working through the security system rather than cloning a fob.
For the large majority of Trax years this does not require a dealer. On a 2015-2022 car we cut the HU100 blade, program the ID46 chip in the OHT01060512 remote, and test start. On a 2024-2025 car we build the HYQ4ES proximity fob from the VIN, pair it, and confirm push-button start before we finish.
Information We Need for a Trax Key
- The year of your Trax, which tells us the original flip-key car versus the redesign right away.
- The VIN, usually visible through the lower corner of the windshield, so we can confirm the exact part.
- How many working keys you have, since a spare from a working key is a different job than a lost-all-keys.
- Whether the car has a start button (proximity) or a key you physically turn (flip key).
- A photo ID and the registration or title, so we can verify the vehicle is yours before programming.
- Whether the trouble is the key, the remote buttons, or the ignition turning, so we bring the right tools.
The Case for a Second Trax Key
If you still have one working key, a planned spare is the smart move before you need it. With a working key as the authentication seed, adding a second is a short job whether it is a flip key or a proximity fob, and a Trax running on a single key is one loss away from the longer all-keys-lost process. We make and program spares at your home, a campus lot, or wherever is convenient.
When to Use a Locksmith vs the Dealer
A Chevrolet dealer can make a Trax key, but for most years that means getting the car there, waiting for an appointment, and leaving it on their schedule. As a mobile locksmith we bring the blanks, chips, flip keys, fobs, and programmer to wherever the car is parked and match the generation on the spot, which matters a lot on a model where the two eras share so little. The rare case that needs manufacturer coordination is something we flag at the VIN stage.
Common Trax Situations Around Statesboro
Example. A student at the Statesboro Crossing locks the only flip key inside a 2018 Trax while loading bags. We get them in, then recommend a spare HU100 key so a single key is never the only key again.
Example. An owner near Georgia Southern University ordered a fob online for a 2024 Trax but received a part for the older flip-key car, which would never pair. We confirm the generation by VIN and program the correct HYQ4ES fob on-site.
Example. A driver off Northside Drive loses all keys to a 2020 Trax. We read the VIN, cut the HU100 blade, program the ID46 chip, and confirm start before we leave.

Common Chevrolet Trax Key Questions
Can you make a Chevrolet Trax key without the original?
Yes. For the large majority of Trax years we make a key with none in hand by reading the immobilizer data and building from your VIN. On 2015-2022 cars that means cutting the HU100 blade and programming the ID46 chip; on the 2024-2025 redesign we pair the proximity fob through the security system.
Why did my online Trax fob not fit my car?
The 2024 redesign shares almost nothing key-wise with the 2015-2022 Trax, so a part for one generation will not work on the other. Ordering by name alone gets the wrong system every time, which is why we confirm the generation by VIN first.
How do I know which Trax key I need?
It comes down to the generation. The 2015-2022 cars use a remote flip key with an ID46 chip, and the 2024-2025 cars use a proximity push-to-start fob. Whether the car has a start button is the quickest tell, and we confirm the exact part by VIN.
My Trax fob stopped working. Is it broken?
Often not. Trax remotes and proximity fobs use a CR2032 coin cell, and a weak battery is the most common reason a remote stops responding at a distance. If a fresh cell does not fix it and the engine still will not start, the key likely needs to be re-paired.
Why is my older Trax key hard to turn?
On the 2015-2022 flip-key cars that is usually a worn ignition cylinder rather than a bad chip. Years of use wear the lock, so the HU100 key sticks or will not turn even though it is correct. We diagnose it at the car and tell you whether a fresh blade or ignition service is the fix.
