So I just bought a 2008 corvette, and I have found it has issues with not recognizing the fob. I replaced the battery, and it still won't recognize the fob from my pocket. It will just flash, "no fob detected". But if I put it near the glove box, it will usually start.
Anyone have issues like this, even after replacing the battery?

 

And does anyone have the instructions for FOB programming?

 

Try this link on replacing batteries, it might be weak battery you replaced.

I, literally, did that five minutes prior to the post. Unless you're trying to suggest that the new battery is weak.

 

I have an 08 and had an 06. I had same issue and it seemed my Iphone would somehow affect the FOB detection. I know it sounds strange but it is true. Try it with your cell phone no where near your car.

 

If the act of putting the fob near the glovebox makes it work, no amount of reprogramming the fob will change that.

It's most likely that some electronics in the car is causing the interference. Be sure you don't have any cell phones plugged in inside the cabin, or any other strong electronic devices.

A slight possibility is a bad fob-detecting antenna. There are several in the car.

 

odds are its the battery. verify its not in upside down and you have the smooth sided button battery CR2032.
next is there interference with phone or charger or any other device that didnt come with the car.
third...
since you have a 2008... does your last digits of your vin end between these numbers? if yes then its possible you have a recall, see link posts #8..

Elmer made a checklist (click and open).. http://forums.corvetteforum.com/atta...-checklist.pdf

note: your fob does not need to be programmed if the 'slot trick' works. that means the car knows your fob so no programming required. if neither fob works in the glove slot, then yes maybe programming would help. keep in mind, if the fob's used to work and the glove slot wont recognise them, then reprogramming probably wont help because first step is to erase them from car, then add them back in. i wouldnt ever erase them unless you KNOW they are good fobs!!

 

What I want to know, is what can be done about the rcdlr.
Ps: my tires sensors and such work

 

they can be replaced but, i'd do everything else first.
questions

do you have 2 fobs? no, then buy another and risk progamming them. if the new one works but old one doesnt then its the old fob thats just bad!

you have 2 fobs and they both act badly and you replaced both batteries, i'd start checking to see what in the new car was added that has electronics that might be causing interference. anything and everything. including something you have on your person or have in the car. remember you said your new car, so what did the seller add that messed up interference?

do you have a recall for your 2008 per the link i sent? if your in the recall list, free fix!!

rcdlr replacement aint gonna be cheap nor easy, to figure out which went bad and then replace.

 

sending you a private message, it will have a parts list showing the 4 recievers.

you can verify with a dealership that these are the ones and order and replace them if you wish. again, i'd leave that to the very last resort..

good luck

 

i'd verify with a parts expert here or at a dealership first, but from what i can gather, part 5 (4 required) is the antenna for fob reciever.

the antenna and its connector and wiring could in theory be bad, but again, last resort.

 

you answer my questions on #7 & #9 , then i'll consider answering yours

you in recall vin range? you have 2 fob? both (2) fobs act badly? any devices that came with your 'new 2008' that wasnt there during its manufacture?

 

*Battery is new, in correctly, and is the correct model.
*I do not have a number two fob, so I cannot test that.
*Car is not in the recall.
*no aftermarket items or devices in the slots.
*fob only works when placed near glovebox
*if I shut the car off, it will no longer recognize the fob
*it will lock the car with me in it, with the fob

 

since your fob will work when in the glove compartment slot..

you should purchase a 2nd fob.
go through the programming procedures for the new 2nd fob.

note that the car will think its the 3rd fob, because someone out there in the world has the 2nd fob (and can get in your car and start it anytime they want).

after programming your new fob, see if it works fine. if it does, then i would say your fob you have now is bad.

if both fobs only work in the slot, and since your sure that there is no interference, you have a bad receiver. in my opinion.

you cant prove you have a bad receiver until you verify that a new fob works badly also.

there is 4 antennas in the car and also a main receiver, that receiver is about $143 (item #1 in following link) and a dealership with the proper equipment has to change it because it has to be programmed and only they have the tech2 to do it. so your talking 2 hrs+ labor so almost $400 in that one part (not counting the 4 antenna which probably are good)

i want you to try this... try placing the fob on the dash right over the antenna , which is in dash, almost to the windshield, just to left of the speaker grill. if you get it there you are within 4 inches of that antenna and i'd think (unless it triangulates all 4 antenna) it should pick up the fob better. just a test for fun.

here is a link for a new fob (item #3)

instructions that dealership will use to replace your receiver (your you said not in recall).. see #8..

well i read fine print on recall. i guess it doesnt matter your vin is outside recall range because the time has expired anyway. recall fine print said... What We Will Do: To correct this condition, your Chevrolet dealer will install a new module for the keyless access system. This service will be performed for you at no charge until October 31, 2008.

 

Like I said, I do not place the fob in the actual slot, I simply place it near the glovebox itself. I have never had to go so far as to place the fob in the actual slot.
Also, I can unlock and lock my car from over 50 feet away, if that information is of any value.

 

i stand corrected, yes , you said that. well, my only fear is that the prior owner has tweeked/modified/added something that is causing interference. but, who know, things do fail so might be bad fob, bad antenna(s), bad receiver. actually i think receiver is probably a bad term, i think its more of a processor, but anyway..


good luck

yea, you know thats something i have been wondering about. there are 4 'antenna'. one in the back end, to open hatch. 1 by each door, to open door. 1 in/under dash, i suspect that its the one for the starting of the car. but, i havent found a good answer yet. to start the car, does it use all 4 antenna or just the one in/under dash...

you find that out and we both have learned something

 

I'm also having an issue with the navigation not reading the navigation disc

 

As ChevyDave said, the first thing I would recommend is to buy a second fob. You are testing fate to have only one. Seeing how that second fob works is a significant step in diagnosing the problem. Unless you know that it was destroyed, there is a fob out there somewhere that will open and start your car. The fact that you can open the trunk or unlock the car with the fob buttons at 50 feet away means that the fob battery is installed properly and is at a full charge.
My guess is that something is interfering with the fob when it is in your pocket. This is common with cellphones, chargers and the like. Try a different pocket or a different placement....but get another fob as first order of business.
Your current problem is not programming related, so don't mess with that until you get another fob. Then you will want to use the long procedure to wipe all fobs and set the two that you will have as #1 and #2. Read the instructions carefully and don't jump in ***** nilly...or you could end up with no fobs that will work.

I believe that the system uses signal from all the antennae and compares the relative strength at each to determine the actual physical position of the fob...then it makes a decision whether to start the car or tell you to go jump in a lake. I think this is the case because my car is very good at discerning the position of my fob. With the top down, I can hold the fob an inch or so inside the window at the top of the door...and the car will start. If I move it just a couple of inches outside the door...literally three inches or so from where it was before, the car says no. It is extremely precise and seems to me that it must be using all the antennae in order to do this.

 

The most frustrating part is the fact that it will lock the car with me in it, or it will simply ask me if it should stay in accessory mode because it doesn't detect fobs.
And I have a fob ordered.
