Replacement Remotes for 4103LX Systems

The pair ensures a spare is available immediately.

For Owners of Compatible Avital Systems

These remotes suit drivers needing to replace or duplicate transmitters for a 4103LX-based alarm installation.

Questions about this item

Will the 7143L remotes work with my existing 4103LX alarm system without reprogramming?

The 7143L remotes are designed as direct replacements for the 4103LX system, but they typically require programming to sync with your vehicle's existing alarm module.

How do I verify the 7143L remotes are functioning correctly after programming?

After programming, test each of the four buttons on both remotes to confirm they trigger the expected lock, unlock, remote start, and trunk or auxiliary functions on your vehicle.
