: Key not detected

So yesterday during rush hour on the way home on 270 North I correctly figured there was a state cop on the shoulder due to the extra slowness of the traffic. Does he pull over the guy who slams on his brakes to move out of the HOV lane? Nope, after I passed him he rushed up the shoulder, popped out and flashed me to pull over. $70 for no front plate, must have been a slow day.

My problem was when I turned on the flashers and turned off the car I saw a Remote Key Not Detected message. The whole time I was pulled over I couldnt start the car but could unlock/lock the doors even with the fob out of my pocket, on the console, in my hand etc. The cop hung with me for several minutes after I received his parting gift while I tried to start the car. I set off the alarm, got out and back in used the physical key nothing. Less than a minute after he finally pulled away everything was ok and I havent had a problem since.

Is there something in that Crown Vic which could have caused this problem? I didnt have my Escort so I dont know if he had radar running or not but he did mention we were being video and audio recorded. Possible some interference? What other issues could this cause?

Your fob battery may be getting low. You can get transient failures (i did with my 08 CTS) when the battery is weak. Best thing to do is to stick the fob in the slot in the console. I think the rfid chip is powered by the car instead of the battery
when it is there so it should detect the fob even if the fob battery is dead. I think all fob/rfid systems have a special place to put the fob specifically for this situation. My vette has a place in the glove compartment. I think this special place is also where you would program a new fob too.

Sometimes security systems get glitched.

And remember, he'll run out of tickets before you run out of money. Don't put a plate on.

There should have been nothing in the Vic that caused that to happen.

Smiles... +1. Will gladly pay the fine before I drill holes in my front fascia.

I wouldn't say that. Cop cars have a ton of electronics in them that will emit powerful radio interference, that combined with a low FOB battery likely was the issue.

My sentiments exactly. Ive been seriously considering registering in Delaware where we have a place just to get away from Maryland taxes and fees. Good thing is they only use rear plate.

Trust me...I know. Low battery? Likely. RFI from equipment in the car? Doubtful. The frequencies from a radar unit or a mobile radio aren't even close to those is an RKE fob.

The symptoms you describe indicate jamming. If you could not start the car until he left, the fob battery is not going to gain any charge when the cop leaves. I ran convoy escorts in Afghanistan and to prevent remotely detonated roadside bombs, we had a major broad spectrum jamming package. Some high end cars around the embassy did not do well around our trucks while we were running the jammers. It seems pretty extreme but who knows what the highway patrol are running these days, I know law enforcement has benefited from a lot of the technology we were testing in Afghanistan.

Thanks for the information, if I'm ever pulled over and I get the "Remote Key not Detected" message I'll probe the officer about it. I have a military tag so that kind of breaks the ice whenever I get stopped.
