Pontiac Aztek key types & programming facts
Pontiac Aztek models in this range use a conventional metal ignition key, with later models using a PK3/B99PT‑style transponder key for the immobilizer system. Remote locking is handled by a separate keyless entry fob that can be programmed to the vehicle using an onboard procedure involving the ignition and driver door lock switch, without a scan tool.
Key types used on the Aztek:
- transponder chip key (PK3 / B99PT style mechanical key with embedded transponder) (2005)
- non‑remote transponder ignition key plus separate keyless entry remote (2001-2005)

How we validate this guide
Year coverage comes from our consolidated vehicle programming dataset. Route-level programming status is reviewed against internal route sheets and available manufacturer, security-access, and professional tool references. Exact button sequences are marked source-verified only when we have year/equipment-specific support; where a year is labeled “route verified, steps vary,” we confirm the exact fob, trim, and prompts before programming. Reviewed for route and safety by Mohammad H. Abdelhadi, ALOA-Certified Master Locksmith.

Common questions
Does my 2001-2005 Pontiac Aztek use a separate remote and key?
Yes. The Aztek uses a separate keyless entry remote plus a traditional ignition key; later years use a transponder PK3/B99PT‑style key for the immobilizer.
Can I program a replacement remote for my Pontiac Aztek myself?
Yes, these years support onboard programming of the keyless entry remote using a sequence with the ignition and driver door lock switch.
What kind of key blank is listed for a 2005 Pontiac Aztek?
Key suppliers list a B99PT PK3 transponder key for the 2005 Aztek, indicating a PK3‑type immobilizer system.
Can you program a Aztek key fob without going to the dealership?
For most years, yes - the route is onboard relearn or an OBD tool, both of which a mobile locksmith handles at your location.
Does this program the remote only, or the transponder key too?
It depends on your key type. Tell us your FCC ID and we will confirm.
What if my year says professional programming required?
Those years need a programmer or security access; we bring the tool to you and program it on site.
How much does it cost?
It depends on year, key type, and whether you have a working key. Call (833) 439-8636 for a firm price before we dispatch.
