Autodata examines key fault

In this regular column, Autodata’s Technical Team share their fixes to common problems raised through Autodata’s technical helpline, available to all UK customers.

2017 Jaguar E-Pace erratic operation of keyless entry/start system and warning message ‘smart key not found’ displayed.


We are having difficulty diagnosing a fault with the keyless entry/start system on a 2017 Jaguar E-Pace. Intermittently the customer is unable to lock/unlock the vehicle using the keyless entry/start system. No trouble codes are stored, remote control battery has been replaced and basic wiring checks to the keyless entry/start system control unit are OK. We are hesitant to replace any components in case a software update will fix the fault. Can you help?


I have consulted with my colleagues on this issue and they do remember a previous report. The fault you have described affects Jaguar E-Pace models 2017 onwards and is caused by a faulty remote control signal receiver. Inspect the remote control signal aerial lead for damage. If no damage is found, fit a new remote control signal receiver. Ensure the remote control signal aerial lead is routed correctly as shown. This should rectify the fault.
