On my little remote thingy the trunk opening button stopped working mysteriously. The one on the drivers side door still works. Everything else on the remote works still (i think). I didnt check the alarm button recently. Any ideas? Maybe I need to reprogram the remote to the car again???

 

Hold it down or press harder. Sometimes mine doesnt work until i press harder or hold it down.

 

maybe the battery is low...

 

check battery

 

If not get a new remote.
