PRELIMINARY INFORMATION
Subject:
Information on Poor, Limited, Reduced Remote Keyless Entry (RKE) or Remote Vehicle
Start (RVS) Range
Models:
2014 and Prior GM Cars and Trucks
Condition/Concern
Some customers may comment on poor or no transmitter range when using the remote keyless entry (RKE) and/or
remote vehicle start (RVS). In some cases, the range has been limited to a few feet.
Some aftermarket devices can cause frequency interference, which may affect the operating range of the RKE and/
or RVS functions.
Recommendation/Instructions
Note: The information contained in this PI is not meant to single out any one device, but to provide additional
information that may be useful for diagnosing issues that do not have other diagnostic methods to identify root case.
Inspect for any aftermarket devices installed or stored in the vehicle. Examples (which are shown in the photos
below) may include:
• Cell phone or USB chargers plugged into an accessory port
• Wireless gate remotes
• Wireless winch remotes
Please look at ALL accessory ports in the vehicle, e.g. instrument panel, inside the center console, rear of center
console, rear cargo area on utilities, etc. In some cases, wireless remotes have been found under seats, inside the
glove box, in the center console, in other storage areas, etc.

concern.
Customer Information
If the root cause is identified as a NON-GM Accessory product, explain to the customer that the aftermarket device is
limiting the range and it should not be used/located in the vehicle.
Warranty Information
If the root cause is identified as a NON-GM Accessory product, a warranty claim should NOT be filed against the
repair; rather, this should be a customer pay item.
