Doors not unlocking with key fob

Hi guys, my e46 m3 key fobs don't unlock doors but it makes the unlock sound when pressed. I use the key to open door. The trunk does unlock and the center console does not unlock doors. Has anyone encountered this too? Appreciate your input. Thanks

Is this happening with both sides of the car? When you press unlock are both sides stuck or is one side unlocking and the other not... I had this sort of problem...the solution was to replace the door lock module on the faulty side.

Hope this helps

Hi! Both doors are not unlocking but the trunk unlocks. Also, they don't unlock when I push the center console lock? Appreciate your input!

Ok I will check the fuses first and then the actuator. Do you know if there is an actuator on both front doors? Seems weird that both actuators would go out at the same time if it's not a blown fuse.

Actuator or GM5 - I suspect the actuators more as they continue to make the sound.
A little research on your part will reveal all.

Are the actuators the same as a module that another responder suggested? Thank you

I'll guess you are referring to DoubleApexCa's comment on the door module. I assume he is referring to the actuator/lock mechanism but only (s)he knows for sure.

It is quite unlikely for both actuators to fail at the same time hence the possibility of the GM5 module which controls both of them. However if they failed at different times then it is the actuators.

Yes I was referring to his comment. I recently purchased the m3. I never found out if the locks failed at the same time or not. Do you think that I should start with the GM5 module first? Thanks

If the lock actuators are still making the whirring noise then its probably is the lock actuators. So don't start with the GM5 module. I recommend you source new ones and you should be good for the next 10 years.
