Condition/Concern
A customer may comment on any of the following complaints:
- Intermittent no crank
- Intermittent no start, or start and stall
- Security / Theft light / Message
- Poor or no RKE range
- Keyless or passive entry/start inoperative
- No Fob Detected message

Note: On vehicles equipped with keyless/passive start, the vehicle will start if the fob is placed in the fob pocket.
In most cases, these concerns cannot be duplicated.
The above systems use Radio Frequency (RF) to transmit information. Some aftermarket devices cause Radio Frequency Interference (RFI), which can "jam" the radio frequency being transmitted.
Listed below are a number of aftermarket devices that can cause RFI. In many cases, these types of devices will be attached to the customer's
key ring and could be removed from the key ring or from inside the vehicle when the customer drops the vehicle off for service.
- Vehicle immobilizer keys from other vehicles
- Keyless access transmitters from other vehicles
- Interstate/bridge toll passes
- Gate/door passes to allow access to pools, driveways, entry doors, etc.
- Community/parking access cards
- Fuel station speed passes
- Building access swipe cards/ transponder devices

Additional items to be aware of:
- Aftermarket LED dome, tail, turn, stop, strip, floor, door, Logo, head lights
In many cases, when the LED lighting is turned on it can interfere with a RF signal. Example, RKE inoperative after the first fob button press. When the RKE fob button is pressed the dome lights may turn on, which if equipped with an aftermarket LED dome light, it can interfere with any additional fob button presses.
- Certain cell phone chargers
- USB power banks
- USB flash lights
- Fans (12 volt or 110 volt)
- Any type of USB, 12 volt or 110 volt chargers
