The remote of my car (mira, 2015) not working

[pwuser156881422593]

I got a dent on the bumper of my Mira. I got the dent removed and got it painted. After the paint and polish the remote is not working. The light on the remote key is working, but the doors are neither getting locked nor unlocked with the remote. Can someone figure out what may have happened?

What has that repair go to do with the remote / keyless entry. Check the remote battery first.

Check the chasis ground connection to body, specifically the pieces which were taken off for painting.

Idk but something does, got my door rubber changed from sultan khoo and remote stopped working ever since.
Car gets manually locked and the speedometer light stays on for few seconds before going off(with remote it goes instantly off)
Got my foot boards and bumper repaired it took three days when it came back the remote worked but only once.
Not a cell issue.
checked all door locks including rear the problem is something else
