Frequently Asked Questions

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

Yes. We create new Cadillac 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 Cadillac 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 Cadillac model and security system generation.

Is a locksmith cheaper than the Cadillac dealer?

Yes — typically 30-50% less. Cadillac 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 Cadillac key replacements?

Yes. All Cadillac 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 Cadillac Locksmith Service in Dallas-Fort Worth

    Cadillac is a Dallas-Fort Worth staple — Escalades on Preston Road and out in Southlake, XT5 and XT6 crossovers up the Tollway, CTS and ATS sedans everywhere, and DeVille, DTS and SRX owners who never traded up. Very little of it needs a dealer visit. The Global A cars — CTS, ATS, STS, XTS, SRX, CT6, ELR, XLR, XT4, XT5, XT6 and the 2015-2020 Escalade — learn a new key over plain OBD with no dealer PIN. The Global B cars, meaning CT4 and CT5 from 2020, the GMT1XX Escalade from 2021 and the Lyriq from 2023, take a CAN-FD adapter and 24-digit ECM and BCM security codes, and we do that in your own driveway.

    Cadillac Key Technology Explained

    Cadillac's immobilizer families do not line up neatly by year, so the model name alone never settles which key a car needs. GM PK3, Megamos fixed-code ID13, covers the 2000-2005 DeVille and DTS and the 2000-2002 Eldorado — a B99-PT blank on the P1106 keyway. PK3+ is a different chip in a similar key: Megamos crypto ID48 on the 2003-2007 CTS and on the 2004-2006 SRX with its B115-PT blank. GM Circle Plus, Philips ID46 on a PCF7936, runs the 2006-2011 DTS, the 2007-2009 SRX, the 2008-2014 turn-key CTS and the 2007-2014 GMT900 Escalade — which is a turn-key truck whose OUC6000066 keyless remote is a separate, uncut fob rather than a smart key. Keyless-access smart prox starts earlier than people expect: the 2004-2009 XLR and the 2005-2011 STS are already fob-in-pocket cars on ID46, well before the push-button CTS arrives in 2008. Global A smart prox then covers CTS, ATS, XTS, SRX, ELR, CT6, XT4, XT5, XT6 and the 2015-2020 K2XX Escalade, all ID46 Philips Hitag2 (the K2XX is listed as Hitag2 Extended, PCF7961E). Global B is the real break: CT4 and CT5 from 2020, the GMT1XX Escalade from 2021 and the Lyriq from 2023 run NXP Hitag-Pro ID49 over CAN-FD — not ID46, and not reachable with a plain OBD cable.

    Cadillac Models We Service Most Often in DFW

    Cadillac Escalade & Escalade ESV

    Three generations, three different jobs. GMT900 (2007-2014) is a turn-key truck: 10-cut B111-PT blade, Circle Plus ID46/PCF7936, with the OUC6000066 remote as a separate fob that is not cut. K2XX (2015-2020) is Global A push-button, ID46/PCF7961E, HYQ2AB at 315 MHz or HYQ2EB at 433, all-keys-lost over OBD with no dealer PIN — estimate 12-35 minutes. GMT1XX (2021-2026) is Global B on CAN-FD with an ID49 Hitag-Pro YG0G20TB1 fob and 24-digit ECM and BCM codes — estimate 25-45 minutes.

    Cadillac CTS & CTS-V

    Three systems wear one badge. 2003-2007 (GMX320) is a PK3+ Megamos ID48 blade, B99-PT or B112-PT, cut to code. 2008-2014 (GMX322) splits inside a single generation: the base turn-key car is a B111-PT Circle Plus ID46/PCF7936, the keyless car is an M3N5WY7777A smart prox at 315 MHz. 2014-2019 (GMX520) is Global A prox on HYQ2AB (315 MHz) or HYQ2EB (433 MHz). None of them needs a dealer PIN.

    Cadillac ATS, ATS-V & XTS

    ATS and XTS are both Global A throughout — 2013-2019 ATS on the Alpha platform, 2013-2019 XTS on Epsilon II. The 2013-2014 cars use NBG009768T at 315 MHz; 2015 onward moved to HYQ2AB (315) or HYQ2EB (433). The ATS is listed with both ignition types: base turn-key trims take an HU100 bladed key rather than a prox fob, so the ignition type gets verified against the VIN before anything is ordered.

    Cadillac SRX

    The first generation changes chip family mid-run. 2004-2006 is a B115-PT blank with the Megamos ID48 and an L2C0005T remote; 2007-2009 moves to a B111-PT with the Philips ID46 Circle Plus and an OUC6000066 remote. Both are double-sided GM wafer, cut to the GM code, no common Lishi. The 2010-2016 second generation is push-button on NBG009768T at 315 MHz, where the driver door decodes with a Lishi HU100 for the emergency blade.

    Cadillac XT4, XT5 & XT6

    All three are Global A, 433 MHz, ID46. XT5 runs 2017-2026, XT4 2019-2026, XT6 2020-2026. HYQ2EB is the early fob and HYQ2ES takes over from 2020, with the XT6 primarily HYQ2ES. All-keys-lost is an Autel OBD job with no dealer PIN and a door-cycle relearn (IM508/IM608 on the XT4 and XT6), plus the Lishi HU100 on the driver door to decode the emergency blade.

    Cadillac CT4, CT5 & Lyriq

    The Global B sedans and the EV: CT4 and CT5 from 2020, Lyriq from 2023, all YG0G20TB1 at 433.92 MHz on NXP Hitag-Pro ID49. All-keys-lost needs the Autel IM508/IM608 with the CAN-FD adapter, which is mandatory here, plus 24-digit ECM and BCM codes from third-party calculation, a door-cycle relearn — 12 minutes on the CT4 and CT5 — and two keys written.

    Common Cadillac Key Problems We Solve

    Online fob arrives and the car refuses it

    Almost always a frequency or FCC mismatch. HYQ2AB is 315 MHz and HYQ2EB is 433 MHz and both are listed for the same models, 2020+ XT4/XT5/XT6 use HYQ2ES, and the 2021+ Escalade, CT4, CT5 and Lyriq use YG0G20TB1. We match the FCC printed on your original fob, or work it out from the VIN, before a part is ordered.

    2021+ Escalade quoted as a plain OBD key

    Global B is not Global A. The CAN-FD adapter is mandatory, the ECM and BCM 24-digit codes come from third-party calculation rather than a GM server, and the 12-minute door-cycle is unavoidable. The all-keys-lost estimate on the GMT1XX is 25-45 minutes, against 12-35 minutes on the 2015-2020 K2XX truck that looks almost identical from the outside.

    No key code stamped anywhere on the vehicle

    On push-button Cadillacs the driver door is the only external lock and nothing is stamped, so buying the code by VIN is dealer-only with proof of ownership. We decode the door cylinder in place with the Lishi HU100 v.3 and cut the emergency blade from that reading.

    Dead fob battery and the car will not start

    The Escalade has a transmitter pocket that reads a dead fob, and it moves by generation. The 2015-2019 truck has it in the face of the center console, pointing down — slide the fob in key-ring up. The 2020 model year moved it to the front cupholder. The 2021+ GMT1XX has no console pocket at all: the fob goes in the front cupholder buttons-up, and 2025+ uses the rear cupholder. Then brake and press START.

    How Our Cadillac Key Replacement Process Works

    1. 1

      VIN and generation check before we dispatch

      We establish Global A versus Global B and turn-key versus push-button first. A 2020 Escalade needs no dealer PIN at all; a 2021 needs the CAN-FD adapter and 24-digit ECM and BCM codes. That one fact sets the part and the tooling, which is why we quote from the VIN rather than from the model name.

    2. 2

      Mobile van to your DFW location

      Driveway, office garage, apartment lot or roadside anywhere across Dallas-Fort Worth — 20-30 minute response across DFW, 24/7. Nothing on this list requires a tow.

    3. 3

      Decode the lock and cut the blade

      Push-button cars: Original Lishi HU100 v.3 GM 8-cut on the driver-door cylinder, then cut the emergency blade to the decoded bitting. The 2007-2014 GMT900 Escalade: the warded Lishi GM B111 Z-keyway 2-in-1 and a 10-cut B111-PT. DeVille, Eldorado, the 2003-2007 CTS and the 2004-2009 SRX are double-sided GM wafer with no common Lishi, so those are cut to the GM key code.

    4. 4

      Write the key to the immobilizer

      Global A: Autel all-keys-lost over OBD, no dealer PIN, door-cycle or 30-minute relearn — the K2XX Escalade estimate is 12-35 minutes. Global B: CAN-FD adapter, read the ECM code, enter the 24-digit ECM and BCM codes, 12-minute door-cycle, keys written two at a time — the GMT1XX Escalade estimate is 25-45 minutes.

    5. 5

      Full function test before we leave

      Push-button start, remote start, liftgate and glass release, panic, the emergency blade in the driver door, and the dead-fob transmitter-pocket start. The vehicle stays on a 12V maintainer through any relearn — a strong, charged 12V is called for on both the 30-minute Circle Plus wait and the Global B door-cycle.
