Ford Ecosport 2015 petrol. Key fob works randomly. After using car, the key does not locks/unlocks remotely. When i leave it for few hours the fob works perfectly. Been to service centre and have changed remote battery, car battery, reprogrammed key, upgraded car software and got car checked using company diagnostic software. Replaced dasboard, BCM and other related module from similar model car and there was no change in status. Checked wiring and fuse. Everything was fine. But the key fob works randomly. Also the battery discharges over night. The fob works then. When battery is low and the engine is not turned ON for some time - atleast 5 hours- Fob works.
If somebody can help to fix the issue, it would be great.
Thanks

Have given my car to the service centre. They did different diagnostics but couldn't get hold of the solution. Finally, today the ignition switch was replaced and miraculously the problem seems to have gone. Thankfully i hope i am done with it for Now.
