Symptom/Vehicle Issue: Remote Keyless Entry (RKE) Functions Do Not Work, Intermittent
Vehicle Response When Using the RKE, Key Not Programmed, Adding Remote Start

Customer Complaint/Technician Observation: The owner complains there is intermittent
vehicle response when using the RKE buttons and or no vehicle response. The technician may or
may not be able to duplicate the concern.

Repair Procedure: If the vehicle is setting Diagnostic Trouble Codes (DTCs) relating to Passive
Entry (PE) or the remote start systems use the diagnostic codes as a first step to verify no antenna
related issues that may be related to key performance issues.
Examples: B1A76-11 Remote Start Antenna Circuit-Circuit Short to Ground
B1A76-13 Remote Start Antenna Circuit-Circuit Open
B1A71-13, B1A72-13, B1A73-13, B1A74-13 B1A75-13 Passive Entry Antennas 1,2,3,4,5
Circuit Open

If no codes: Before replacing the key fob use steps below as a guide to proper diagnostics.
Using the scan tool verify the RFHM module data shows the vehicle has both key fobs programmed
for the subject vehicle.
- If the key fob brought in with an issue is different from the key fobs programmed to the
vehicle (not listed in the programmed section), and it is OEM part, follow proper procedure to
pair new/additional key fobs.
If the key fob of concern is shown in the programmed list to the subject vehicle, follow the below steps
prior to any warranty related key fob replacement:
1. For fobs, with or without LED:
i) Remove the coin battery from the key fob.
ii) With a Voltmeter verify that the coin battery has the correct voltage.

iii) If the battery is low (below 2.6V), please replace the battery.

2. Test the performance of the key fob remote signal and its battery with the
ATEQ VT56 tester to ensure good signal strength. Use the distance range performance at
different vehicle parked locations to further test the RKE performance.
3. Fobs that have continued issues after testing and/or a replacement battery, verify the
vehicle has no aftermarket LED light installations either externally or internally that may affect
a consistent RKE signal.

3a. Confirm the intermittent operation of the RKE is not just at one location and
appears at different parked vehicle locations to eliminate the possibility of
outside interference affecting the RKE signal performance.
4. If the Radio Frequency Hub Module (RFHM) has been upgraded to the RFHM with remote
start, follow the programming procedures in Service Library (SL) – 08 Electrical /8N – Power
Systems / Power Locks / Transmitter, Integrated Key Fob / Standard Procedure. Proper
programming is required for system operation and warranty.

NOTE: Review Master Tech:
Key FOB or TPM loss of signal / poor performance.
