Speedometer pegged after battery disconnect

[Dayukie]

Disconnected my battery overnight in hopes of resetting an error on my CD player that has stopped working.
After hooking up the battery my speedometer is pegged and my keyless remote has stopped working. It did lock and unlock about 3 times but now it does nothing. Can someone point me in a direction? DId I fry something?

you may have to relearn your remotes. I had the speedo thing happen after disconnecting my battery. It will fix itself after you hit 20-30mph. Not sure about the remotes as I have an aftermarket alarm on mine.

Try the relearn process for your key fob. Click on the link in the 4th post of this thread, he goes through the process step by step-

That is exactly what happened. I got up to about 30 mph and it popped back and started working normally. WEIRD!

Try turning the ignition on and taking a magnet and try to drag the needle back to normal. It may sound crazy but mine did the same thing and thats how I was told to fix it and it worked.
