Keyless Access Not Working

[David Armstrong]

I have a C Class Premium which has keyless access however I’m experiencing some problems.
The car now will not unlock without using my key fob however the doors lock when you touch the sensor.
There is also a similar problem with the boot it used to open withoutusing the key fob by the boot handle but now won’t. Also there is a button on the boot to lock the car this won’t work however the boot close button does.
I have checked the settings on the car are activated which shows it’sactivated. I’ve also changed the batteries in the keys.
Any ideas what the cause / causesof the problems

Have a try at deactivating, locking, let the car go to sleep fully (around 20 minutes) then unlock reactivate and see how it goes.

as above, and please check the quality of the batteries you replaced the originals with- quality Varta, Panasonic etc should be used (the pound shop ones look tempting but are crepe)
