Chevrolet Equinox Key Replacement Cost: $90 to $550 by Year

The Equinox we replace keys for most is the 2018 to 2024 third generation, where the HYQ4AA smart proximity fob is standard on push-button trims. The locksmith range for that fob is $200 to $360. The dealer range is $300 to $480. Both numbers include the cut emergency blade, the proximity pairing to the vehicle, and a verification drive. The base L and LS trims on this generation kept a turn-key ignition and the cheaper OHT01060512 flip key, at $110 to $230 from a locksmith.

If your Equinox is a 2010 to 2017, you have the integrated flip key, FCC ID OHT01060512. This is the cheapest modern Equinox key to replace: an OEM-spec blank runs $25 to $55 online, and a mobile locksmith cuts and programs it for $60 to $120, so a fully working spare is $85 to $175 versus $190 to $320 at a dealer. It is the same flip key as the 2013 to 2016 Malibu and the Cruze, so any GM-capable locksmith carries it.

The 2025 fourth generation is the newest and the priciest. The YG0G21TB2 proximity fob is standard on every trim, so there is no cheaper base-trim key to fall back on. Locksmith range $260 to $420, dealer range $380 to $550. This fob uses the current GM proximity platform and an ID49 chip, so confirm your locksmith carries current GM tool coverage for the 2025 Equinox before booking.

Generation by generation

Section 02 / Trim split

The base trims and the push-button trims take different keys

On the 2018 to 2024 Equinox, the single biggest thing that changes your bill is trim. Base L and LS trims came with a turn-key ignition and the integrated OHT01060512 flip key you physically turn, and that is the cheaper Equinox key to replace. The higher trims with push-button start got the HYQ4AA smart proximity fob, a one-piece key with no ignition slot. That fob costs more to buy and program.

Before you ring a locksmith, look at your dashboard. A start button and a proximity fob means you have the HYQ4AA smart key. A key you turn in the column, folding out from the remote, means you have the flip key. Quote the wrong one and the price will be off by $80 to $150. From the 2025 fourth generation this distinction disappears, the YG0G21TB2 smart fob is standard on every trim. See the cost-by-make guide for the rest of the Chevrolet lineup.

Frequently asked

1. 01

   How much is a key for a 2012, 2017, 2020, or 2025 Chevy Equinox?

   A 2012 and a 2017 Equinox both use the integrated OHT01060512 flip key, $110 to $230 from a locksmith or $190 to $320 at a dealer. A 2020 Equinox with push-button start takes the HYQ4AA smart proximity fob, $200 to $360 from a locksmith or $300 to $480 at a dealer, though a base L or LS trim with a key slot still uses the cheaper flip key. A 2025 Equinox is the all-new fourth generation with the YG0G21TB2 smart fob standard, $260 to $420 from a locksmith or $380 to $550 at a dealer. Match your model year and trim to the generation table above.

2. 02

   How much does a Chevrolet Equinox key replacement cost in 2026?

   Between $90 and $550 depending on year, trim, and channel. A 2007 to 2009 transponder key is the cheapest at $90 to $190 from a locksmith, and a 2005-2006 non-transponder key is cheaper still. A 2025 to 2026 fourth-generation YG0G21TB2 smart fob is the priciest at a dealer, $380 to $550. The most common Equinox job, a 2018 to 2024 third-gen HYQ4AA smart fob, runs $200 to $360 with a mobile locksmith.

3. 03

   Does the base Equinox use a cheaper key than the push-button trims?

   Yes, on the 2010 to 2024 cars. Base trims with a turn-key ignition use the OHT01060512 flip key ($110 to $230 from a locksmith), while push-button-start trims from 2018 use the HYQ4AA smart proximity fob ($200 to $360). The quickest way to tell which you have is whether the dashboard has a start button and you carry a one-piece proximity fob, or the column has a key slot and your key folds out from the remote. From the 2025 fourth generation the smart fob is standard across the lineup, so there is no cheaper base key.

4. 04

   Can a locksmith program a Chevrolet Equinox key?

   Yes, for every Equinox generation. GM does not lock Equinox programming to dealers, and mainstream locksmith tools (AutoProPad, Smart Pro, GM MDI) cover it fully. The 2007 to 2009 transponder key can even be self-programmed when you still have one working key; the separate remote still needs a tool. The one thing to confirm is the 2025 fourth-gen YG0G21TB2 fob, which uses the newest GM proximity platform and needs current tool coverage, so ask specifically about the 2025 Equinox before you book.

5. 05

   Is the Equinox flip key the same as the Malibu or Cruze key?

   The 2010 to 2017 Equinox flip key is the same FCC family as the 2013 to 2016 Malibu, the Cruze and the GMC Terrain: FCC OHT01060512. The shell and electronics are interchangeable as a blank, but the pairing data is vehicle-specific, so a Malibu flip key will not start an Equinox until it is programmed to that VIN. The 2018+ HYQ4AA smart fob is likewise shared with the Traverse and Blazer, and the 2025+ YG0G21TB2 fob with the Traverse, Colorado and Tahoe. Order by the exact FCC ID printed on the back of your existing key.

6. 06

   What is the cheapest way to get a spare Equinox key?

   On the 2010 to 2017 flip-key Equinox, buy an OEM-spec OHT01060512 blank online for $25 to $55, then pay a mobile locksmith $60 to $120 to cut and program it. Total $85 to $175 versus $190 to $320 at a dealer. On the 2018+ HYQ4AA smart fob, an OEM-spec aftermarket blank runs $50 to $130 plus $80 to $150 to cut and program. Confirm the FCC ID matches your existing fob exactly, and program a spare while you still have a working key, because all-keys-lost costs more.

7. 07

   What if I lose all my Equinox keys?

   The locksmith or dealer reads the immobiliser code from the Body Control Module, decodes the door lock to cut a fresh blade, then programs every key from scratch. Add $80 to $200 to the standard quote. On the 2010 to 2024 cars, all-keys-lost is doable in your driveway by a well-equipped mobile locksmith, no tow needed. On the 2025 fourth-gen car, confirm the locksmith carries current GM tool coverage for the YG0G21TB2 fob before they roll out.
