In 1990 Oldsmobile introduced the VATS key-lock on the Oldsmobile Toronado. The VATS technology used on the following Oldsmobile models:

  • Oldsmobile Toronado 1990-1993
  • Oldsmobile Regency 98 1991-1998
  • Oldsmobile LSS 1999
  • Oldsmobile Eighty Eight 1992-1999
  • Oldsmobile Cutlass Supreme 1994-1998
  • Oldsmobile Aurora 1995-2000


In 1999, Oldsmobile started to use PASSkey technology on the Oldsmobile Venture. Most Oldsmobile OEM keys stamped with a PK or PK2. The technology were slowly adopted on other models and the PASSKey II systems followed shortly.

PASSKey III and transponders

transponder keys In 1999 Oldsmobile Silhouette started to use the Circle Plus transponder and in 2005, Uplander started to use the PASSkey 3 transponder. These transponders have 10 cuts that operate the door and the ignition. Transponder technology were slowly adopted on other models.

Why does Oldsmobile use transponder keys?

How does Oldsmobile 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 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 you program a transponder key yourself?

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

Oldsmobile uses a simple on-board procedure to add keys for the PASSKey III vehicles using one already programmed key. First you need to have a blank key or buy cut key online. Once you have the key in hand, follow to following instruction to program a dublicate key yourself.
