Keyless Entry - Intermittently Inoperative/Poor Range
File In Section: 08 Body and Accessories
Bulletin No.: 01-08-52-006
Date: October, 2001
TECHNICAL
Subject:
Reduced Operating Range of Remote Keyless Entry (RKE) System With Blower Motor Running At High Speed (Diagnose and Install External RKE
Receiver, If Necessary)
Models:
2001 Oldsmobile Alero
2001 Pontiac Grand Am
Condition
Some customers may comment that the Remote keyless Entry (RKE) System will not work at times or has an extremely poor range.
Cause
This condition may be encountered on vehicles produced prior to November of 2000, with the non-remote mounted RKE module system. This will
become a concern for those customers who start the vehicle to allow it to cool or warm and let it sit in the driveway with the doors locked. They then try
to enter the vehicle using the key fob and find they are unable to unlock the doors. The limited range is the result of electromagnetic interference (EMI)
from the blower motor. The faster the blower is running, the more limited the working range of the RKE system key fob becomes.
Diagnosis
An aid to the diagnosis of this concern would be the following:
^
The customer's key fob is easily separated from the vehicle's key.
^
The vehicle has a remote starter system installed.
