Question about 2006 Hummer H2
1)Check that the battery is OK in the remote control.
2)That the inside Sensor is not obscured or damaged.
Does the central locking work if the doors are locked with the key?
If not, it sounds as if it is the central locking relay isn't working.From memory this relay is located under the dash centre console.
Start with the cheapest possible solution first. Fit a new battery in the remote, about a £1 from most places.
But change it quickly, and bear in mind that when these batteries go completely flat, the fob usually loses its settings and has to be reprogrammed by a dealer. £40-50 or more for the pleasure.
The best way to avoid that is to be in the habit of using the remote a decent distance from the vehicle where practical, and then you can easily notice when the battery gets weaker, as you have to get closer before it works.
Thanks for contacting Fixya.
