Land Rover Part Number: LR099140 - Passive Start Module
LR099140 is a Passive Start Module that forms part of the vehicle's anti-theft alarm and passive keyless start system. Fitted to vehicles with smart key systems, the module processes and decodes signals from smart keys, communicates with the vehicle security network and immobiliser, and authorises the starter only when a valid key is present. It links the door locking and ignition systems to the alarm and immobiliser logic; faults or incorrect coding can prevent keyless entry or deny engine start, so correct replacement and professional programming are required.

Frequently Asked Questions
The LR099140 Passive Start Module manages vehicle-side security for keyless entry and push-button start. It decodes authenticated signals from smart keys and exchanges authorisation data with the vehicle immobiliser and security network to allow starter operation only when a valid key is detected. Because incorrect coding or module faults can disable keyless entry or prevent engine start, replacement must be followed by correct programming and diagnostic verification.
