Hummer 2007 H3 - Manual (Page 89)

Changes or modifications to this system by other
than an authorized service facility could void
authorization to use this equipment.
At times you may notice a decrease in operating
range. This is normal for any RKE system. If
the transmitter does not work or if you have to
stand closer to your vehicle for the transmitter to
work, try this:
• Check the distance. You may be too far from
your vehicle. You may need to stand closer
during rainy or snowy weather.
• Check the location. Other vehicles or objects
may be blocking the signal. Take a few steps
to the left or right, hold the transmitter
higher, and try again.
• Check to determine if battery replacement is
necessary. See “Battery Replacement”
under Remote Keyless Entry (RKE) System
Operation on page 89.
• If you are still having trouble, see your dealer
or a qualified technician for service.
