My dealer re-programmed my keys and I still have the problem 30% of the time. Anyone else having this problem?

I have not had that problem - though my car is only 2 weeks old. I drive it every day/several times a day.

I only drive it myself and don't use Fob #2. Is one of your a problem, or when both are in the car? Several other folks had problems when both fobs were in the car.

I get "not recgonized" about 50% of the time :banghead
and without the slightest moving it always works the second attempt.
dealer claimed it was working fine......
I'll be having another 'talk' with them soon! :boxing

A couple of suggestions;
1. keep the key fob away from other keys in your pocket/purse that may block the signal. I have a habit of keeping alll of the keys to my vechicles in one pocket and occasionally I need to move the key fob to the top of my pocket before anything will happen.

2. Have you replace the battery in your fob??

3. Don't go in the water with your fob or get it wet. I will screw it up exspecially if there is chlorine or salt water involved.

Other than that I suggest you try another dealer to fix the problem. Maybe some in our group have had good experiences with a dealer close to you and can suggest who to talk with. If that doesn't work, have your selling dealer talk with the Cadillac rep to get you somebody to help you work through the problem.


Good Luck.

I have the no fob come up every time a get gas at mylocal mobil gas station. I just wave the fob at the glove copartment and it works every time, with either fob. At this Mobil station tou can here the microwave signal on the radio if the radio is turned on. Any other it works perfect, and I had the since last turkey day.

There was a pretty long thread on this a while back. Basically there were some quality issues with the fob system on a few (not a lot) of the XLRs. There were also some issues with using the fob at a Speedpass-type place.

To see if your system is working properly is a bit time consuming. Basically take the fob out of your pocket, put the fob on top of the center console and start the engine (in park, of course). Open and close the drivers door (I know this sounds silly) and watch the driver information center display. You should get no error messages (Fob Not Found, specifically). Try opening and closing (with a slight delay after closing) the door about 10 times. If you get no error messages, then this is a good thing.

Now, move the fob to the driver's lap and repeat. Then try a few different driver locations (hand, pocket, etc). Each time repeating about 10 (or more) times. If the system is working right you maybe should get one error message. If you get more than that, check your battery. If the battery is OK and you are getting error messages at multiple locations and while the XLR is parked at different places, then it is time to see your dealer. You may have to convince the dealer. I did that by making a map of the percentages of failure at different locations within the XLR.

The solution for my XLR was to replace the control module for the keyless system. This is an 8 hour job (I kid you not). Since that time I get (at most) 1 error message in a month. 99% of the time the system works perfectly.

FYI,
Here is something to keep in mind if you traval alot. You should take both of your key fobs with you. If you loose one or one becomes inop. you can not start the car even if you have the "key" to get into the car. I called ONSTAR to ask if they would be able to help me out if this happen. All they can do is unlock the doors and call road side assistance to have the car taken to the nearest cadillac dealer.
Now I called Allen Kulbersh "Mr. XLR" to get his take on this. "This man know this CAR inside out" He told me it was a security feature and the best out there. You can ONLY have two key fobs programed and any one time. If someone came up to you with a gun and told you to get out of the car and stole your car and did not get the fob from you he could drive off but when he turned off the car it would not start... By this time you would have called the police and ONSTAR they would be tracking it all the time and should be able to recover it ASAP.
If a fob is stolen or lost you should have the other one reprogramed when you get a new one. I ask if all dealers had key fobs IN STOCK he said he did not know but if I travaled a lot I may want to buy one and NOT have it programed just leave it in the car. Then if something happen to one of them you have one that the dealer can program for you. Might save you some time.
Any way its something to think about.

It might be nice if GM could come up with a way for the "KEY" to start the car and only have just the basics work so you can drive it to a dealer or get home. Maybe have it work for ONLY 24 hours... That would get you out of a bind also.

Thank for the tip on traveling! I get the error messages too, but when i try a second time it usually works. The system does seem a little flaky, especially through jeans or heavy pants.

fredw, if you are getting error messages more than once or twice a month while the XLR is at different places, I strongly urge a trip to the dealer. That is not how the XLR should opperate.

Thanks, I think I will.. I just always dread leaving my car at the dealer.

Got my XLR just last week, (twelve months since ordering), had no problems the first couple of days,but NOW I have the problem of Key Fob not being sensed EVERY time it's in my pocket. Salesman (excellent service) stopped at my home yesterday and I demonstrated the problem. I have to take the fob out of my pocket and locate it above or on the center console for it to operate. I suspect that the metal around the gearshift etc is blocking the sensor. Cadillac should have located the sensor on the Driver's side.

This IS a problem. Nothing is pissing me off more than having to take the key fob and place it next to the glove box 50% of the time I start my car. Its already been re-programmed.

However, I do belive the door must be closed before pressing the start button which seems to help.

Cadillac needs to address this problem or go back to a key. The Vette owners are not going to be happy with this.

Yes, there is a problem with *some* of the key systems. However, I would strongly disagree with going back to a key. Once fixed that is one of the best systems on the XLR. In its correct state, the system is very reliable.

If the fob is not working that way you would like (aka reliably) the owner really should press the dealer to make it work right. Make sure you ask the dealer if they have talked to XLR tech support. They were the ones who suggested changing-out my keyless system. Every since the new system was installed, it has worked extremely well.

Have you tried putting in a new battery? Sure worked wonders for me!

Solved my FOB problem. The cell-phone charger cord, plugged into either the cigarette lighter or the auxillary causes a "double sensor" to the system and both are rejected. I tried just locating the cord below (on the floor) but that didn't do the trick, I had to unplug the cord from either outlet. Now it works fine

Intresting, I have a cell phone charger also always plugged in. I will try unplugging and see what happens.

I had the same problem with my key fob and the problem later turned out to be a bum battery. The battery was replaced and then no problems since. Fingers crossed.

I think you discovered the problem! When I connect my lighter into my cell phone my key fob is not recognized when I disconnect it is!

I hope someone at GM is listening as this is a real problem. I have a Samsung phone what kind is yours?

It sounds like you may have found a cause. However, before my fob system was replaced I had the fob problem whether the charger was plugged in or not. With the new fob system, the fob works with the Motorola plugged-in and with it disconnected.

There may be more than one cause to this issue. As I am constantly reminded at work, complex systems fail in complex ways. The XLR is a complex system (to say the least!).

Again, the best way to make sure Cadillac knows about this is to take the XLR into the dealer and make sure the dealer contacts XLR tech support.
