Lost your Viper key fob or need to program a new one? Don’t worry, programming your Dodge Viper key fob can be a straightforward process you can accomplish yourself in just a few minutes. This guide provides simple, step-by-step instructions for programming key fobs for both Gen I and Gen II Dodge Vipers, ensuring you’re back on the road quickly.
Step-by-Step Guide to Programming Your Viper Key Fob
Before you begin, ensure your Viper’s alarm system is disarmed. The programming process varies slightly depending on whether you own a Gen I (1992-1995) or Gen II (1996-2002) Viper. Follow the instructions below that correspond to your Viper generation:
For Gen II Viper Key Fobs (1996-2002):
- Locate the EEM Connector Wire: Find the EEM (Electronic Entry Module) connector under the dash, positioned on the left side of the transmission tunnel, directly above the accelerator pedal. Removing the knee bolster can improve access. Look for a loose green wire, often taped to the harness of the EEM connector. Specifically, for 1996-1998 models, this is pin C13. For 1999-2002 models, you will be grounding Terminal 1 of the DLC (Data Link Connector), which is the OBD2 connector under the dash above your left knee.
- Ground the Wire: Using a low amperage fused jumper wire for safety, ground the identified green wire (or DLC Terminal 1 for later Gen II models) to a solid body ground. Use an ohm meter to confirm a secure ground connection.
- Enter Programming Mode: Turn the ignition to the “run” position while keeping the green wire grounded.
- Confirm Programming Mode: The dash LED will flash to indicate the system has entered programming mode. If it doesn’t flash, double-check the wire, ground connection, and ensure you maintained the ground while turning the ignition to “run”.
- Program the Key Fob: For all Gen II Vipers, press and hold both buttons on the key fob transmitter simultaneously for 10 seconds. A triple horn chirp will confirm that the EEM has accepted the key fob programming.
- Program Additional Key Fobs (Optional): If you have additional key fobs to program, you must program them during this same session. Gen II Vipers can accommodate up to 4 key fobs.
- Exit Programming Mode: Turn the ignition off and remove the green wire from the ground.
- Test: Test the arm and disarm functions of your newly programmed key fob.
For Gen I Viper Key Fobs (1992-1995):
- Locate the Program Wire: Find the green “Program” wire with a bullet connector located next to the SAM (System Anti-theft Module) and RKE (Remote Keyless Entry) modules. This is situated under the driver’s side instrument panel.
- Ground the Wire: Using a fused jumper wire, ground the green “Program” wire to a solid body ground. Verify a good ground connection with an ohm meter.
- Enter Programming Mode: Turn the ignition to the “run” position while keeping the green wire grounded.
- Confirm Programming Mode: The dash LED should flash to indicate programming mode entry. If not, re-check the wire and ground.
- Program the Key Fobs: For Gen I Vipers, press and release the arm or disarm button on one key fob, and then repeat for any subsequent key fobs you wish to program.
- Program Additional Key Fobs (Optional): Program all desired key fobs in this session. Gen I Vipers typically support up to 2 key fobs.
- Exit Programming Mode: Turn off the ignition and disconnect the green wire from the ground.
- Test: Verify the arm and disarm functions of all programmed key fobs.
By following these steps, programming your Viper key fob should be a breeze. Enjoy the convenience of your working remote once again!
