Does Buick use transponder keys?

Buick VATS keys

In 1990 GM introduced the VATS key-lock on the Buick Reatta. The VATS technology used on the following Buick models:

  • Buick LeSabre 1992-1999
  • Buick Park Avenue 1991-1996
  • Buick Reatta 1990-1992
  • Buick Regal 1994-1997
  • Buick Riviera 1990-1993
  • Buick Roadmaster 1994-1996


In 1995, Buick started to use PASSkey technology on the Buick Skylark. The technology were slowly adopted on other models and the PASSKey II systems followed shortly. Most Buick OEM keys stamped with a PK or PK2.


transponder keys In 2005, Buick started to use PASSkey 3 transponder technology on the Buick LaCrosse. The technology were slowly adopted on other models. The PASSKey 3+ systems followed shortly and today, Buick uses it on most models. Most Buick OEM keys stamped with a PK3, PK3+ or just a "+".

Sidewinder transponders

In 2010, Buick started to use sidewinder transponder keys with encrypted signals on the Buick LaCrosse. Every year, GM is changing the key-lock on more models to this high security sidewinder.

Buick smart keys

From 2007 few Buick models adopt the Passive Entry Passive Start (PEPS) with push-button start ignition. The keyless entry devbice contain a transponder chip and is an optional feature on specific vehicle.

What is a Buick transponder key used for?

car anti-theft Buick transponder keys used mainly as an anti-theft technology. The immobilizer configured to accept each unique programmed key by a code. When a key with unmatched code turned in the ignition, the vehicle will not start.

How does Buick immobilizer works?

How does Buick VATS key works?

The VATS key uses a resistor pelet in key "shaft" and a Theft Deterrent Module to validates the key. There are only 15 different ressistances possible for the key. If the TDM recognize the resistance value, it will send a valid key signal to the PCM allowing it to start.

How does PASSKey works?

In Passkey system is actually not a transponder, but very similar to the VATS! The Theft Deterrent Module validates the resistance of the chip in the key. The PASSKey includes more that a 100 resistances.

In addition to the resistance check, PASSKey also use the PASSLock system as an extra safety feature. The PASSLock module and measures and record voltage data through a magnitude sensor placed on the ignition. It basicly check the proper key cut profile and determines if the cylinder is aligned. If the PASSLock recognize the key it will allow the car to start. This is effective when cylider is broken, damaged or picked usually by a thief trying to hotwire the vehicle.

How does PASSKey II works?

PassKey II works like the PassKey I, but the TDM is built into the BCM instead of the ignition. The BCM sends a digital start/no start signal to the PCM over the data bus. One more change from PASSKey I is that halting the engine done by the fuel system instead of the ignition.

How does PASSKey III works?

The Passlock III is actually the first transponder used by GM. The chip is located inside the plastic covering of the key and stamped "PK3" on the metal blade. The ignition lock cylinder contain an antenna that reads the transponder data and sends a it to the PCM. If the PCM recognize the code from the key, it will allow the engine to drive. Some higher end models use a key fob instead of metal blade.

Later version of the PK3 called PK3+ or + have the same infrastructure and fuctionality as the PK3 system. The only difference is that the PK3+ use an encrypted transponder and requires dedicated programmers.

Can I program a transponder key myself?

VATS/PASSKEY I/II duplication requires special VATS reader and is possible and not recommended as a DIY project. For more information read here about VATS keys.
