Hope that someone can help. My '04 XLR has begun giving a "NO FOB DETECTED" message in the DIC at times. Sometimes holding the fob in front of the dash will help. At other times it does not and I must put the fob in the glove box slot which will then let the car start. I have replaced the fob battery which seems to help but not all the time. Still get the message occaionally. The original factory warranty is expired, but I have the GM extended warranty. Took the car into the dealer to check for the problem, they found nothing and charged me a labor charge since nothing was found. Said that if they had found a problem there would have been no charge. Can someone help?

Maybe you purchased an old battery. It's usually best to buy batteries at a place that has decent turn around of the product (Wal-Mart or Target).

I've bought "new" batteries at Radio Shack and had them poop out in no time. Target seems to be my best purchasing place.

A new battery every spring for both remotes seems to be the recipe for eliminating the "No Fob Detected" warning.

Thanks for the suggestion. Bought the battery at a bettery store, and had them test it before installation.

I had a similar problem with one of my fobs.. Same sort of symptoms, changing the battery seemed to help for about a week and then it was back to taking the keys out of my pocket or placing the fob in the glove compartment slot. Brought it to my dealer and they ran a diag on it (the fob itself) and said it came back with an "antenna fault".. They said they "cleaned the contacts", (not sure what contacts they were talking about, maybe the batt contacts) and "changed the battery".. It seems to have solved the problem for now... We'll see how long it lasts...

I would always sugest replacing the batteries every 2 years as the remote is always sending a signal, so it is always powered up. Long before you get a "No Fob Detected" you usually find the door does not quite release the same as before, or the declid releases, then pulls down.

Allen, I still have the first batteries in the fob of my 04 XLR and it still works like new. I almost never touch any button of the fob beside I want to open the trunk and I`m outside of the car bcause the car opens and locks itself as you know and that propably gives a long battery life.

I ovserved when I`ve had it new and the fob was in the left pocket of my pence "no fob detected" since than I allways have the fob allways in my right pocket and no more problem since!!!!!

Hans

All good suggestions. Not all 2032 batteries are created equal though. I use the Duracell "Medical" grade 2032s @ $3.50 and have had no problems. Clean the fob 's electrical contacts with a pencil eraser or a swab dipped in isopropyl alcohol each time you swap out the battery.

Cheers,

Harry,
That is the reason I tell every client NEVER keep the remote in your left pocket of your coat or pants. The receiver is under the speaker on the top of the right side of the dash. By keeping it on your left side, it is the farthest from the receiver. The distance is kept short for security purposes. The same reason stands that you should never leave anything plugged into the 12 volt outlet on the center stack or in the console when out of the vehicle.

Most people start to have battery issues around 2 years and before, it varies of course and you are the exception. It must be the German air!

I hope to finally meet you in June!

"Security Purposes"? Please tell me more; how does placing the fob in your right pants pocket vs. your left pants pocket bolster security? What if you are not wearing/carrying the fob in your pants pockets?

This is the first I am hearing that my $80,000 american-made "halo car" can't sustain a cell phone charger plugged into its 12 volt outlet overnight without consequences. What's up with that??

Okay, now I am really confused .... first ... I never put my car key in a pocket ... it is in my purse on the floor of the passenger side ... so, how is that compromising security ... but then, clearly, I am out of the loop on this one, because I didn't know that there was any security system in the X anyway ..... :confused And why would it be triggered when you are IN the car opposed to being triggered when you are OUT of the car? :confused :confused

Am I the only one not getting this???

Common sence tells me if you wish to shorten the distance from the driver to the module, move the module to the left side of the car.

Using the same common sence, Ruth Ann is correct; the module and the fob begin negotiating long before you get into the car.

What are we missing?

But Mark, if they move the module to the left side you might get "no fob detected" if you carry your fob now in the right side pants pocket:lol

alltogether I have no problem with this, had it only 2 -3 times when the fob was in the left side (when my X was almost new).

On Friday I parked my STS V near a factory and had my sun roof partly open, after about 3 minutes the alarm went on, now I know it have to close this.

Good this don`t happens when we have the tops down on our XLR`s and leave the cars:glol

... Good this don`t happens when we have the tops down on our XLR`s and leave the cars:glol

Harry (Hans)

Well, that brings up a whole new point .... :rolleyes

But, don't let me get side-tracked here ... I would definetly be intested in the key fob vs security explanation .... so, my remote is always sending a signal? What is it sending it to if I am shopping in, say, a mall? I would think that it sends a signal only when I push a button to activate it from a distance, (ie, open trunk) or when I am in approach distance of the vehicle .... and, if I am reading right, if I have my cell phone plugged in, that is another security breech or it is draining the fob battery and how can it do that - if again my fob is out of range of the vehicle? And are both fobs being affected?? Ya' need to help me out here .... I'm still just a little bit blonde! (woven like silk among the grey .. :glol )

Well, Ruthie, to answer one of your questions, yes, the FOB is always broadcasting, it's the nature of the beast. It doesn't know when it will be called upon to open your door to get in, so it's always "on the job." I believe that is the "security" part of the previous post.

I would assume the same broadcasting would pertain to both FOBs, each FOB is unaware the other exists, so they are both doing their thing, which is continuous broadcasting.

Have no idea why something can't remain plugged into an onboard receptacle. :confused

Floyd

Ok, Lets start with the 12 volt plug in. If you leave SOME chargers plugged in, it can cause an elctro static field around the charger, thus blocking the signal from the remote that is on the left/drivers side of the console, to the receiver, under the right speaker on the passenger side of the dash.

It has happened a number of times nation wide,, I personally have seen it 3 times in the last 4 1/2 years. It depends on the charger, it also doesn't matter on some if they are connected to anything. Some chargers are always powered on, even when no device is connected to them.

#2 The XLRs remote is always on sending a signal, when you are within 3 feet of the exteriors 3 antennas that are built into the (drivers door, passenger door and the deck lid) the signal is picked up by the antennas. Thats why when the batteries are low, you may have an issue oppening the doors or the deck when depressing the rubber trigger pads.

If you are like Ruth Ann that keeps the remote in her purse on the passenger side, you would most likely never have an issue of"No Fob Detected" warning. But, if you keep the remote in your left pocket (farthest point from the receiver) and your batteries are getting weak you could experience a "No Fob Detected" warning.

In simple term regarding a plug in cell phone charger, use it when driving, un plug it when out of the vehicle.

If there are three antennas and one links the receiver via the drivers side door, having the remote in your left pants pocket should place it closer, not further way from a reception point, since that is the whole purpose of the antennas, right?

As for the "electro static field" created by low amp battery chargers impeding said reception; well........sounds like that's a case for Myth Busters since that seems like a pretty big design flaw to me, since every vehicle with keyless entry utilizes the same basic technology and I never had a problem with my Corvette which has the same system. I kept a charger for my XM radio modulator plugged in all the time along with my phone charger.

I totally understand the concept of continuous operation/broadcasting; what I'm having a hard time understanding is how placing the receiver on the right side of the dash increases the system's security. Again; if you wish to shorten the broadcast "loop", put the receiver on the left side of the car. In fact, placing it on the right side (again, using common sence) increases its level of confusion if your spouse gets in with their fob.

This brings up another question I've wondered about:

If husband & wife are each carrying their FOBs, does the car know who to set up for as you both approach the car? I'm assuming it would answer to #1 first. OK, husband is driving and gets too sick to drive, hubby & wife change seats, wife is now the driver, I suppose she would have to push the #2 button so things set up for her, right?

Floyd

Sounds right to me. Thanks for the PM

Yes, and the system will also warn you if you get out and your spouse stays in the car. It thinks you are locking your keys in the car.

WOW!!!!

What a mind/vivid imagination--what happened to your previous wives??? Never mind. . .

Anyway, not too many wives could fit in our beloved trunks!!!

I just find it very hard to believe a system that utilizes three different antennas designed to pick up the fob signal as it approaches the outside of the car can be offset by an electro-static field generated by an interior source. I realize the receiver is located on the right side of the dash, but like any receiver; it needs an antenna to capture the signal. You could mount that unit in the trunk, as long as its antenna is out in the open it will function just as well as if it were mounted on the hood.

Oh my gosh, Standby .... you have me laughing so hard I have tears running down my face. :glol

Now - do I have to worry about Ray putting me in the trunk, and if he does will I still be able to open the trunk with my own FOB???? Or do I still have to be within 3 feet of the receiver? :eek

~~

I will wait to see how this FOB vs 3 antennas thing gets explained ... this is pretty interesting actually, seeing as we travel ALWAYS with at least one cell phone plugged in ..... and what about the Valentine .... is that a FOB battery drainer too? :confused

Thanks for all the replys to my note regarding the fob. I think that my problem is that the #2 FOB is not transmitting sufficiently at times. I plan to have the dealer run a test on it when I next go in.
By the way -- it was Bud Abbot and Lou Costello who did the "Who's on first..." routine I loved it.

Each of the three antenna's (Driver's Door, Passenger's Door, Trunk) senses for a FOB in order to allow access to that respective area. If you are close to the passenger's door then it unlocks. If the trunk, it unlocks. There are separate zones. Of course, if you have it set up to unlock both doors when you unlock the driver's door, then approaching the driver's door both doors unlock.

I have found that standing in the doorway with someone else sitting in the driver's seat is not good enough to allow the car to start. I assume then that there is another "antenna" for a cabin "zone" of the car that enables the ignition feature. Why this antenna is not as close to the ignition switch is beyond me. Why it is closer to the passenger's seat than the driver's was a surprise to hear. I obviously don't know all that went into the location selection, but I let the engineers and designers do their job of creating this beauty - and I do my job of loving to drive it.

Hope this helps to clear the fog a little rather than add to it.

Ben.

Bill, at least I got the right time period. Thanks
