Chevy Suburban Key Replacement
Chevy Suburbans have been on Dallas–Fort Worth roads since the 2007 era, and across 2 key generations this model has used 2 different key systems — remote-head / flip; smart-proximity. Whichever yours is, DFW Keys 4 Cars cuts and programs it at your location, 24/7: spare keys, lost-everything replacements, fob programming, and lockouts. Call (214) 717-6398.
About Suburban Keys
The table below is our verified key reference for the Chevy Suburban — model years, key types, and the transponder/immobilizer family each generation uses. Generations overlap at boundary years, and trim levels (keyed vs. push-to-start) can differ within the same year, so we always confirm the exact part by VIN before dispatching.
| Model / Generation | Years | Key Type | Transponder / Immobilizer | Blade / FCC |
|---|---|---|---|---|
| Suburban | 2007–2014 | remote-head / flip | Philips Crypto 2 / Hitag2 / ID46 | B111 / HU100 |
| Suburban | 2015–2020 | smart-proximity | Hitag2 Extended / ID46E / NXP PCF7952E, PCF7961E | HU100 emergency insert |
Security System & Immobilizer
GM security moved from VATS resistor keys through PassLock (sensor in the cylinder, plain key) to PK3/PK3+ transponders, the ID46 “Circle+” era, and today’s proximity fobs. Knowing which system your year uses is half the job — and we confirm by VIN.
On the Suburban specifically, the immobilizer families we see are: Philips Crypto 2 / Hitag2 / ID46, Hitag2 Extended / ID46E / NXP PCF7952E, PCF7961E. A key that is cut correctly but not programmed to this system will turn the locks and never start the engine — programming is the half of the job that matters.
Which key does your year have?
- 2007–2014: remote-head / flip — Philips Crypto 2 / Hitag2 / ID46 (B111 / HU100)
- 2015–2020: smart-proximity — Hitag2 Extended / ID46E / NXP PCF7952E, PCF7961E (HU100 emergency insert)

Chevy Suburban Key FAQ
I lost the only key to my Suburban. What now?
We come to the vehicle, verify ownership, cut a new key from the VIN, and program it on-site. No tow, no dealer wait — this is our most common Suburban call.
My Suburban is push-to-start. Can you really program that outside the dealer?
Yes. Late-model Suburbans (2015–2020) use a proximity smart key on the Hitag2 Extended / ID46E / NXP PCF7952E, PCF7961E system — our trucks carry the fobs and the programmer. We cut the emergency blade too.
