Frequently Asked Questions

Can you make a GMC key if I lost all my keys?

Yes. We create new GMC keys from scratch even with zero working keys. We access the immobilizer system directly, erase old key data, and program your new key as the primary. All-keys-lost service is the most complex scenario but we handle it on-site without towing.

How long does GMC key replacement take?

Standard key with transponder: 20-30 minutes. Smart Key programming: 30-45 minutes. All-keys-lost scenario: 45-90 minutes depending on the GMC model and security system generation.

Is a locksmith cheaper than the GMC dealer?

Yes — typically 30-50% less. GMC dealerships charge premium labor rates plus parts markup. MyKey uses OEM-equivalent key fobs at wholesale pricing, and our mobile service eliminates towing costs. Same quality programming, significantly lower price.

Do you warranty GMC key replacements?

Yes. All GMC key replacements come with a 1-year warranty covering the key fob hardware and programming. If the key fails due to a defect within 12 months, we replace it at no charge.

    About Our GMC Locksmith Service in Dallas-Fort Worth

    GMC is a work-truck brand in a work-truck metroplex. Sierra 1500 and 2500HD crews park on jobsites from Balch Springs to Alliance, Yukon and Yukon XL Denalis run school pickup in Southlake and Frisco, Savana vans haul trade inventory across the Metroplex, and Acadia, Terrain and Canyon fill the driveways in between. The catch is that the badge tells you almost nothing about the key. A 2003 Sierra has no chip in its key at all. A 2024 Sierra wants a CAN-FD adapter and two generated 24-digit security codes before a fob is even acknowledged. A 2026 Savana is still running the same ID46 Circle-Plus blade the vans got in 2008. We work from the VIN, not the nameplate.

    GMC Key Technology Explained

    GMC runs five distinct immobilizer systems across the 1996-2026 span. Oldest is GM PassLock - the sensing sits in the ignition lock cylinder and the key carries no chip - on the GMT800 trucks and SUVs, the S-series Jimmy and Sonoma, the Safari and early Savana vans, and most first-gen Canyons. The 2002-2009 Envoy is its own island: GM PK3 / PassKey III with an ID13 chip on a B99-PT blade, and some 2007-2009 Envoys shipped with no transponder at all, so the key gets verified before it is cut. From 2007 PK3+ arrives as the Philips ID46 '46E' Circle-Plus B111-PT on the GM Z keyway - Sierra and Yukon GMT900 and Gen-1 Acadia from 2007, then the Savana van from 2008, which keeps that system through the current 2026 models. Running in parallel on the HU100 8-cut keyway is GM Hitag2 Extended ID46 (PCF7937E / PCF7961E): K2XX Sierra and Yukon, Terrain 2018-2021, Canyon 2015-2022, Gen-2 Acadia. The 2010-2017 Terrain sits on that same HU100 keyway, but its record carries a plain Philips Crypto ID46 with no PCF part number and no Hitag2 Extended label attached. Global B on CAN-FD with NXP Hitag-Pro ID49 fobs is the newest layer, and it is where the 24-digit ECM and BCM security codes enter the picture - Yukon from 2021, Sierra and Terrain and Hummer EV from 2022, Canyon from 2023, redesigned Terrain from 2025.

    GMC Models We Service Most Often in DFW

    GMC Sierra 1500 / 2500HD / 3500HD

    Four systems in one nameplate. GMT800 (1999-2007) is chipless PassLock on a B102 / P1113 blank. GMT900 (2007-2014) is an ID46 '46E' B111-PT blade with a separate OUC60221 / OUC60270 remote. K2XX (2014-2019) is an M3N-32337100 flip on HU100. T1XX splits twice: smart trims are Global A on HYQ1EA for 2019-2021, then Global B on HYQ1ES or YG0G21TB2 with ID49 and a CAN-FD adapter from 2022. WT and Pro turn-key trims run their own track - M3N-32337100 flip through 2021, then a bare HU100 blade plus an M3N-32337200 RKE fob.

    GMC Yukon / Yukon XL / Denali

    GMT800 (2000-2006) is PassLock on B102. GMT900 (2007-2014) is the B111-PT blade. K2XX (2015-2020) is Global A push-to-start - HYQ1AA at 315 MHz or HYQ1EA at 433, no PIN - and it is the Yukon generation with the dead-fob start documented: pocket the fob in the center-console transmitter slot with the opening pointing down, then brake plus START. T1XX (2021-2026) is YG0G21TB2 on Hitag-Pro ID49, Global B over CAN-FD, and its record notes that adding one fob often wipes and relearns the existing one, so keys go in pairs.

    GMC Acadia

    Gen 1 (2007-2016) is a warded GM Z-keyway B111-PT blade decoded with the Original Lishi B111. With one working key, 2007 through roughly 2010 accepts the GM 30-minute onboard relearn - three ignition cycles of about ten minutes each - while all-keys-lost, and 2011+ reliably, need an OBD immobilizer tool. Gen 2 (2017-2023) is push-to-start on HYQ1EA, the Yukon-family fob, part 13508275, not the HYQ4EA. It is also the one GMC entry carrying a documented all-keys-lost estimate: 12-35 minutes.

    GMC Terrain

    2010-2017 (Theta) is a turn-key OHT01060512 flip on HU100 with an ID46 chip and no PIN - and note that a 2017 Terrain is still this generation, a year after the Acadia moved on. Gen 2 (2018-2024) is push-to-start and splits mid-run: 2018-2021 Global A on HYQ1EA (433) or HYQ1AA (315), 2022-2024 Global B on HYQ1ES (434) or HYQ1AS (315) with ID49 and CAN-FD. Gen 3 (2025+) is Global B as well; vendor listings show YG0G21TB2 and our record marks it verify-per-VIN.

    GMC Canyon

    First gen (2004-2012, GMT355) is mostly PassLock on the narrower B110 / P1114 keyway, with PK3+ ID46 transponder builds on a B110-PT that are more common on later and Canada-market trucks. Second gen (2015-2022) stays turn-key on an M3N-32337100 HU100 flip with a PCF7937E ID46 chip; its all-keys-lost is logged as Global A auto-PIN and its add-key path as tool plus PIN. Third gen (2023+) is push-to-start Global B on YG0G21TB2 at 434 MHz, where the code is not free from the GM server and comes from SPS2 or a third-party rolling-code calculator.

    GMC Savana 1500 / 2500 / 3500

    The van is the outlier. GMT600 (1996-2007) is PassLock with no chip on a B102 blank. GMT610 from 2008 is the ID46 '46E' B111-PT Circle-Plus blade on the GM Z keyway - and the van keeps that system through the current 2026 models, long after the trucks moved to HU100 and then to ID49. Programming splits inside the generation: 2008-2010 goes onboard with a working key (insert working key, ON one second, OFF, insert the new key and turn ON), while 2011 and newer needs the tool over OBD.

    Common GMC Key Problems We Solve

    The onboard all-keys-lost sequence erases every fob the vehicle knows

    On the K2XX Yukon (2015-2020) and the T1XX Sierra smart trims, the no-tool AKL path runs three 10-minute cycles and the third cycle wipes all previously known fobs, so any key the owner keeps has to be relearned in that same session. The T1XX Yukon record goes further and notes that adding a single fob often wipes and relearns the existing one. If a working fob exists anywhere, say so before we start - add-key is the shorter path. How many fobs that onboard add-key needs splits by platform: the T1XX Sierra record calls for two already-recognized fobs, while the K2XX Yukon record runs its onboard add off a single programmed fob. Both records document the DIY sequence as US-only.

    Wrong fob ordered from an online seller

    HYQ1EA versus HYQ4EA versus HYQ1ES catches people out. Beyond the FCC ID, the chip itself changed on different dates per platform: Yukon in 2021, Sierra and Terrain in 2022, Canyon in 2023, moving from Philips ID46 to NXP Hitag-Pro ID49. A Global A fob fits the pocket and will never learn to a Global B truck. The FCC ID printed on the customer's own fob gets matched to the VIN build before anything is sourced.

    Security light and no-crank on an older GMC truck

    On PassLock vehicles there is no chip in the key that can fail, because the key never had one. The documented fault path is the sensor in the ignition lock cylinder or a BCM that lost sync, and the documented fix is the GM PassLock relearn - three ten-minute ignition cycles, 30 minutes in total - run only when the cylinder or the BCM lost sync. Selling a chipped key into that fault changes nothing.

    No onboard programming path on the newest trucks

    GM deleted the driver-door-cylinder relearn on the Sierra 1500 from 2023 and the Sierra HD from 2024; those manuals point straight to the dealer. Where the onboard method does survive on T1XX trucks it demands two already-recognized fobs, and the T1XX Yukon has no DIC relearn at all. Each of those cases needs an OBD programmer, and on Global B a CAN-FD adapter with it - a standard OBD cable will not talk to that immobilizer.

    How Our GMC Key Replacement Process Works

    1. 1

      VIN and FCC check before we roll

      We decode the VIN to fix the platform - PassLock, PK3 ID13, ID46 blade or flip, Global A smart, or Global B - and read the FCC ID off the fob you already have, because HYQ1EA, HYQ4EA, HYQ1ES and YG0G21TB2 are not interchangeable.

    2. 2

      Mobile dispatch across DFW

      A stocked van reaches most Dallas-Fort Worth locations in 20-30 minutes, carrying HU100 / B119-PT, B111-PT, B99-PT, B110 and B102 blanks.

    3. 3

      Lishi-decode the driver door and cut

      GM stamps no code on the vehicle, so the lock is the source. HU100 v.3 (GM 8-cut) handles the modern flips and the emergency blades inside smart fobs, the non-warded GM37 / B106 handles the older GM Z-keyway blades, and the B111 handles warded Z-keyway cylinders such as the Gen-1 Acadia. On the first-gen Canyon the B110 keyway is narrower, so GM37 / B106 fit is checked on site. No drilling, and the cylinder stays in the door.

    4. 4

      Program to the immobilizer

      Most Global A GMCs learn over OBD with no dealer PIN, using the Autel door-cycle timer of roughly 10-12 minutes or the GM 30-minute relearn of three 10-minute cycles. The 2015-2022 Canyon is the carve-out: its all-keys-lost entry is auto-PIN, but its add-key entry is logged as tool plus PIN. Global B needs the CAN-FD adapter plus generated ECM and BCM security codes - 24-digit on the T1XX Yukon, 2022-on Sierra and 2022-2024 Terrain records - then the driver door cycled every three to four seconds through the roughly 12-minute timer.

    5. 5

      Test before we leave

      We verify start, the remote functions your trim actually has, and lock and unlock range - plus, on the vehicles that document it such as the K2XX Yukon and the Gen-2 Acadia, the dead-battery start from the console transmitter pocket. On the Global B records that specify it - T1XX Yukon, 2022-on Sierra smart trims, Hummer EV - the procedure programs keys in pairs, so the second key is learned in that same session.

    Why DFW GMC Owners Choose MyKey Locksmith

    Autel IM508 / IM608 with the CAN-FD adapter - the Global B GMCs in our records: T1XX Yukon, 2022-on Sierra, 2022-2024 Terrain, Gen-3 Terrain from 2025, Gen-3 Canyon, Hummer EV
    Original Lishi HU100 v.3, non-warded GM37 / B106 and warded B111 decoding - non-destructive entry to the cut code
    Coverage from chipless PassLock B102 keys through Hitag-Pro ID49 proximity fobs, 1996 through 2026 model years
    Where the Global B record documents it - T1XX Yukon, 2022-on Sierra smart trims, Hummer EV - all-keys-lost is a two-key procedure, so the pair is learned in the one session
    FCC ID and build year confirmed against the VIN before we quote or dispatch
