A No Fob Detected message may be displayed on the Driver Information Center of some 2004-2009 XLR and 2005-2013 Corvette models when attempting to start the vehicle. The engine may not crank/start and the vehicle’s doors may not open through passive entry. However, the vehicle will always start when the Remote Keyless Entry transmitter (key fob) is placed in the instrument panel compartment pocket. This condition may be caused by an internal transistor of the Remote Control Door Lock Receiver (RCDLR) module not operating properly.

To diagnose this condition, be sure the vehicle battery is adequately charged to start vehicle.

Next, remove the battery from the key fob. Using a DVOM, measure the voltage.  Be sure the key fob battery voltage is between 2 to 3 volts. If not, replace the battery. Test operation of the vehicle again. If the vehicle no longer exhibits the condition, the vehicle is repaired.

If the vehicle has a known good key fob (not placed in the instrument panel compartment pocket), press the Engine Start Button and listen for a click noise or a series of click noises from the RCDLR. If there is only one click (instead of a series of clicks), the transistor internal to the RCDLR is not operating properly. For this condition, replace the RCDLR module.

The RCDLR module on the Corvette is located above the radio behind the instrument panel trim on the right side. (Fig. 12) On the XLR, the RCDLR module is located on the top right of the instrument panel under the upper instrument panel pad. (Fig. 13)

  1. I have another question. I have two key fobs for my 2005 Corvette. Right now I have fob #2 in the glove compartment pocket. With fob #1 I can lock the doors and unlock them, get in the car and start it. Even as normal! My question is key fob #2, while in the glove box pocket acting as a replacement for a bad RCDLR Module?

  2. I also hear many clicks. I must open my trunk with the key and then pull the door release chord to enter the car. I then must put my fob in the pocket located in the glove box to start it. Any other ideas will be appreciated.

  3. I have all the same issues. What is the part number of the rcdlr ? And is this different than the theft deterant system.

  4. Mine has a series of clicks but I have to start it from the glove box then rest of day it is good Thanks
