Programming Guide for 1999 Smart Keyless Entry Remote Fob – Cadillac Eldorado

Important Notice: The 1999 Eldorado does not support onboard programming for keyless entry remote fobs. Remote programming must be completed by a qualified automotive technician using diagnostic equipment that interfaces with the vehicle’s onboard computer system.

Programming Procedure:

  • Step 1: Confirm Programming Requirements Review your vehicle’s documentation to verify that remote fob programming must be completed using specialized tools by a technician.
  • Step 2: Ensure Remote Compatibility Before the appointment, make sure the remote you are using is compatible with your vehicle’s system. Using an incorrect remote may result in programming failure.
  • Step 3: Locate a Qualified Technician Find a certified automotive technician who is experienced in keyless entry system programming and has the necessary diagnostic equipment for your vehicle’s make and model.
  • Step 4: Collect Necessary Vehicle Information Prepare the Vehicle Identification Number (VIN), model year, and any available remotes. This information may be required during the programming session.
  • Step 5: Decide on Service Location If the vehicle is operational, it may be more affordable and convenient to drive to the technician’s shop instead of requesting mobile service.
  • Step 6: Schedule an Appointment Contact the technician to schedule a remote programming session. Confirm availability, service costs, and the number of remotes that can be programmed during a single visit.
  • Step 7: Bring Required Documentation Prepare to show proof of vehicle ownership, such as the title or registration, along with a valid photo ID. This is often required if no working remotes are present.
  • Step 8: Technician Connects Diagnostic Tools At the appointment, the technician will use diagnostic equipment connected to the vehicle’s onboard port (typically located under the dashboard) to access the remote programming interface.
  • Step 9: Programming Process The technician will follow secure procedures using the diagnostic tools to program the remote fob into the vehicle’s keyless entry system.
  • Step 10: Confirm Remote Functionality Once programming is complete, test the lock, unlock, and trunk release buttons to ensure the remote is working correctly.

Additional Considerations:

All Remotes May Need Reprogramming: Some systems require all remotes to be programmed at once. Bring all remotes you wish to continue using.

Battery Condition: Ensure the new remote has a working battery before programming begins.

System Capacity: Ask the technician how many remotes your vehicle supports if you’re adding extras.

Programming Duration: The process typically takes between 15 to 30 minutes depending on the system.

Backup Remote Tip: Consider programming a second remote during the same session to have a spare available.
