Slight glitch from what I've found. Has happened to me at the gas pump. One other time while talking outside my car with out opening the doors. If No FOB detected then step out of the car lock and unlock, get back in and try. If still dosen't detect then you need to walk twenty feet away with your key and it should reset.

    But when these fail you need to re-learn your FOS remote. Open the center console, bottom corner you'll find a slot where it fits. Slide it in, press brake and start. Once it starts, remove the remote and your back on track.

Key fob not working


Steve, did you try to remove the battery from the FOB to make sure that is the cause? If you did and you are sure of it, the FOB keeps transmitting even though you are not pressing the button. Have it check by any reputable alarm guy. You don't have to go to the dealer.

No FOB detected


I get this with my car and it is usually because it cannot sense the fob in my purse, so I move the purse to my lap. Other reason is the battery is getting low in the fob and needs replacing - at least that is my experience with my 09 Cadillac STS.

if u mean what i think u mean...that means the battery inside the FOB (thing you use to unlock the doors) is low, take the back off and replace the battery.

I changed my battery in my 2005 cadillac sts, and now it is showing that the starter is locked. fob locks and unlocks the car, but i can't get car to start. what do i do?


you can try this, with the battery connected lock the car using the key fob, make sure no keys are in the ignition. Disconnect the battery again and let it sit for 30 min or so, reconnect the battery and using the key fob unlock the car, it should start, if not repeat the procedure and insert the key into the door lock to unlock the car, both of these solutions should reset the security system. Good luck.

NO FOBS DETECTED
Keyless Entry System Description and Operation

Key Fob Not Detected
When a transmitter authentication is requested, the console passive antenna broadcasts a challenge within the passenger compartment to the transmitter. If the response from the transmitter via radio frequency (RF) is a valid response, the RCDLR determines there is a transmitter within the vehicle. If no response is received, the RCDLR determines that no transmitter is in the vehicle, and NO FOB DETECTED will be displayed on the DIC.
Transmitter authentication occurs during any of the following situation:
• When the vehicle is off and the start button is pressed.
• When the vehicle is off and the brake pedal is pressed (vehicle must be awake)
• When the vehicle is running and any door is opened and then closed.

The first thing to do would be to check for DTC'S - diagnostic trouble code's
DTC B3119, B3120, B3121, B3122, or B3123 is not set.

Important: This condition may be caused by low vehicle battery voltage. If the battery is not sufficiently charged (above 10 volts), the system will have difficulties detecting the fob and the NO FOB DETECTED message will be displayed. Correct the low battery voltage condition to eliminate this condition.
Verify DTC B3119, B3120, B3121, B3122, or B3123 is not set.
? If any of the DTCs are set, refer to Diagnostic Trouble Code (DTC) List - Vehicle.
With the vehicle locked, attempt to passively unlock and enter the vehicle by approaching the vehicle with a valid transmitter and pulling the exterior door handle. The door should unlock and open.
? If unable to enter the vehicle passively, refer to Keyless Entry System Inoperative.
Place the transmitter in the console active antenna pocket and attempt to start the vehicle. The vehicle should start.
? If the vehicle does not start, perform the Transmitter Programming procedure.
While placing the keyless entry transmitter in various locations within the vehicle interior, attempt to start the vehicle. The NO FOB DETECTED message should not be displayed on the DIC.
? If the message is displayed, inspect for any sources of RF interference such as cell phone chargers, power supplies, etc. that would interrupt transmitter and antenna communication. If inspection does not reveal any items causing RF interference, contact the customer and question the customer about the conditions or location where the NO FOB DETECTED condition occurs. Discuss any devices that are normally kept in the vehicle, such as a laptop or cell phone charger, which may have been removed when the vehicle was brought in for service. It may be necessary to explain to the customer how RF interference degrades the performance of the system.
Inspect the external RF antenna connection at the RCDLR. First, gently pull on the coax connector at the module. If the coax comes out, then it wasn't seated properly. Remove and carefully inspect the coax connection for bent blades or a bent center pin. Fix coax connection if necessary and re-seat connector until a "click" is heard. Gently pull on the coax connection to make sure it is seated properly.

Your best bet , dealer !

2005 sts wont start. Says no FOBS detected. Please help?


Are both FOBs doing this? If it's only one I would replace the FOB battery.
NO FOBS DETECTED Message on DIC, No Crank/Start Unless Fob in Center Console Pocket or Remote Keyless Entry (RKE) Button Inoperative (Replace Remote Control Door Lock, Theft Deterrent Receiver Assm) #04-08-52-008

Tell the Dealership to look at this. They should be able to fix it quickly.

Keep us updated.
