TextHow Silhouette Keys Changed Over the Years
First Generation (U-Body)
Pure mechanical security on the earliest Silhouette: nothing more than the cylinder wafers and the cut of the blade. No transponder chip, no resistor pellet, no immobilizer module to relearn anywhere. Our truck cuts a fresh blank at the curb and the minivan starts the same minute. Easiest Oldsmobile job we run.
Second Generation (GM Minivan)
GM rolled the VATS resistor-pellet immobilizer onto the U-body for 1997, and the Silhouette inherited it. The blade itself now holds a small carbon-film pellet set to one of 15 possible resistance bands, and the ignition module checks that value at every start. There is no chip in the key head. EEPROM programming or an on-board procedure handles a fresh key, all wrapped at the curb with the Autel.
Third Generation (Updated U-Van)
The third-gen U-van jumped to PK3 security in 2001. The key now combines a mechanical blade with a one-piece remote head holding three buttons and a Megamos 13 transponder chip. Programming happens through OBD-II with the BCM learning each new key against a manufacturer PIN. Our scan tool handles the whole sequence at your San Diego address.
Identify the Key on Your Silhouette
Plain double-sided blade with a small plastic head. No buttons, no chip, no battery, nothing electronic in the head at all. The cheapest Silhouette key we cut.
Visually similar to the 1995-1996 blade, but if you look closely a small black resistor pellet is pressed flush into the blade itself. That pellet is the entire security; lose it or wear it down and the van refuses to fire.
One-piece remote head key: three buttons up top (lock, unlock, panic), Megamos 13 transponder chip molded into the head, mechanical blade below. CR2032 powers the remote side.
Silhouette Key Pricing in San Diego

Worn VATS Pellet on 1997-2000 Silhouettes
Behind almost every no-start call on a 1997-2000 Silhouette is the VATS resistor pellet drifting out of spec. The ignition reads pellet resistance against 15 possible values; once drifted, the BCM cuts the starter while SECURITY stays lit. We ohm the pellet, then cut a freshly pelleted blank or install a VATS bypass.
Transponder Sync Failure
Crank, security flashing, no fire on a 1997-2004 Silhouette almost always points at transponder data the BCM no longer recognizes. Common triggers: a battery swap in your Hillcrest driveway, a failed DIY relearn, or a previous owner who added a key without clearing slots. Remedy is OBD-II wipe and reprogram.
Remote Fob Battery Drain
The PK3 remote head keys on 2001-2004 Silhouettes burn through CR2032 cells faster than expected, partly sliding-door usage cycles the BCM frequently. A dead cell mimics a broken remote. We open the housing in your driveway, drop a fresh CR2032, verify range. Corrosion? We clone to a fresh shell.
Ignition Cylinder Failure
Loose key, hard to turn, has to be wiggled? That is the cylinder wafers wearing down, and the Silhouette is a known offender. GM issued recall 96V142000 on 1995-1996 vans for this wear. Our fix is a cylinder swap at your San Diego curb with a fresh key cut and matched, so you keep one working key.
Can You Program Your Own Silhouette Key in San Diego?
No programming needed or possible. These are plain mechanical keys with no chip. You just need a correctly cut blank.
Remote-only DIY for the 1997-2004 minivans goes like this: pull the BCM PRGRM fuse, cycle the ignition between RUN and OFF, then hold lock and unlock together for 15 seconds until the van chimes twice. Pairs the remote buttons only. Touches nothing on the VATS or PK3 transponder side; the engine-start authorization still needs our scan tool.
Got one working key already? On 1996-2004 transponder Silhouettes, GM's 10-second relearn adds a spare: turn the working key to ON, back to OFF, then within 10 seconds insert the new key and turn to ON. SECURITY light extinguishes if it took. Lost every key? That path requires manufacturer PIN access and the Autel IM608; phone (619) 876-1271 and we will roll out.

San Diego Trivia Worth Knowing
Strange footnote in GM minivan history: the 1995-1996 Silhouette shipped without any electronic anti-theft at all. While the Cadillac line was already rolling VATS into every car, the Oldsmobile minivan stayed on pure mechanical security right until GM standardized VATS across the U-body in 1997. By the time the Silhouette production line shut down in 2004, the Oldsmobile brand itself was already being wound down for good.
