RKE Functions programming

[Sky King]

This is with my 99 SC-2. Also, I have already read the "How To" on this and I don't see the solution. So any help would be appreciated.

For some reason, all on it's own, the functions performed when you lock or unlock using the RKE fob have changed. For as long as I have had the car, when you selected "lock", it would lock the doors and arm the security system. If you pushed the lock button a second time, the horn would chirp. When unlocking, the first button push would unlock the drivers door only, disarm the security and turn on the dome light all with no horn chirp. To unlock the passenger door, you have to press the unlock button a second time.

NOW for some reason, things have changed and I don't know why. Now, when you press the lock button once, the locks lock, the system arms and you get a horn chirp. When you press unlock once, you get the drivers door unlocked, the horn chirps TWICE and then the dome light comes on. You still have to press the unlock button a second time to get the passenger door unlocked.

Like I said, I did nothing to cause this to change. I really don't like it because no matter what happens, you will get a horn chirp. Because of my work schedule, I am comming and going at some odd hours and I really don't like the horn going off every time I either arrive and lock or unlock to leave. I would like to get it back to the way it was.

No takers on this?

Do you have more than one remote to isolate the problem to the remote or rke system?

I would agree, try another remote otherwise yours is almost 10yrs old and probably needs a thorough cleaning. Some TLC on the old one can do wonders sometimes.

I'll give that a try.

Jump pins #4 and #8 on the OBD 2 connector and see what mode the RKE is in.I bet the horn will chirp four times indicating mode # 4.If your in mode four do the procedure in this video except cycle the key only one time.

If its really bothering you, I would just reprogram the remote.

I just bought another RKE on ebay for $15 and easily reprogrammed two RKE to the setting that I desired.

You might already be aware but their is an instruction manual in how to do this on this website in the DIY section.

Good luck.

First, thanks to all who responded. Next, many thanks to Richpin, your input and video were very helpful and I was able to resolve the problem with the procedure you outlined.

I do still have a question or two if any of you have any idea. FIRST, when I jumpered pins 4 and 8, the horn did chirp as indicated in the video to identify the mode the RKE module was in. BUT, it chirped 14 times, yes I said FOURTEEN. Got any clue what mode that is? Next, any ideas what may have caused this un-prompted change? As I said in my first post, I did nothing. Just one day, I went out to get in the car and bingo, mode change.

As for those who suggested that I try another FOB to see if they did the same thing, I did, and as I suspected, they were no different. And as for the instructions to program a FOB, I really didn't think that would have any effect as that is to program the FOB to match the car, that has no effect on the MODE that the receiving module in the car operates on. The mode is obviously controlled by the module in the car, not the key FOB. Also as I stated in my first post, I did check the instructions given by Wolfman in the HOW TO but I didn't see what I needed.

But again thanks to all who responded. It is back to normal.
