GM VATS Resistor Key Bypass Module Key Value Matched 1986-2004

GM VATS Resistor Key Bypass Module Key Value Matched 1986-2004

Supplied pre-set to your key’s VATS resistor value (1 of 15). Bypass solution for GM vehicles that use the VATS / Pass-Key resistor pellet key (black resistor pellet in the ignition key). This module bypasses the resistor pellet detection circuit so the vehicle can start normally when VATS key-reading issues occur.

What it does: The GM VATS system reads the resistor pellet in the ignition key and sends a “key OK” signal. If the key value is read incorrectly, the vehicle may crank and not start or shut down quickly. This bypass is built to your provided key resistance value to eliminate the pellet-reading failure point.

Fitment:

• Chevrolet: Corvette (1986–1993); Camaro (1990s–2002); Caprice (1994–1996); Impala SS (1994–1996); Lumina (1995–2001); Monte Carlo (1995–1999)
• Pontiac: Firebird / Trans Am (1990s–2002); Grand Prix (1994–1996); Bonneville (1992–1999)
• Cadillac: Allante (late 1980s–1993); Brougham (early 1990s); DeVille (early 1990s through mid/late 1990s); Fleetwood (early 1990s); Seville (early 1990s through late 1990s); Eldorado (early 1990s through late 1990s)
• Buick: Park Avenue (1991–1996); Roadmaster (1994–1996); Riviera (1990–1999); LeSabre (1992–1999); Regal (1994–2004 on some trims); Century (late 1990s–early 2000s)
• Oldsmobile: Aurora (1995–1999); Cutlass Supreme (1994–1997); 88 / Ninety-Eight (1992–1999); Toronado (early 1990s)

What’s included:

• VATS bypass circuit board enclosed in a durable protective housing
• Solder: 1 small spool
• Heat shrink: 2 pieces (correct size and length)
• Instructions: printed installation instructions

How to order (custom value):

• Select your measured key value from the options; we ship the matching pre-set module (1 of 15)

Installation notes:

• Basic wiring and soldering required
• Follow the included printed instructions exactly

Limitations: Bypasses the resistor pellet detection portion of VATS only; a properly cut mechanical key is still required to turn the ignition. Verify your vehicle uses a VATS resistor pellet key system before purchase.
