remote control key wont lock or unlock

[jmccjr]

I recently went to my local auto parts store and on the counter they had a key fob tester. I pointed my key fob at tester and pushed buttons as instructed and the tester lit up. If key fob works but doesn't unlock or lock car, do I have a programing issue with the car?

Sorry about posting in multiple threads. I will stick with this one.

On doing further research I think that I don't have an oscillator missing between the two points. The key fob just needs to be programmed it would seem. Will try some of the techniques mentiond by others on this forum to see if I can re-program the key fob...

Thanks.

Issue: pressing buttons on fob, red light comes on but nothing happens.

Replaced buttons and battery but still the same. Would work if I pressed hard or if I took the circuit board out of the key and press button with thumb with index finger underneath pressing on the battery.

If I hold the edges of the circuit card and press button does not work. Thought it might be battery connections so I removed the battery holder from the circuit card and hard soldered the battery to the circuit card.

Still did not work unless as I pressed button with thumb while pressing underneath against the lower(flatter) of the three chips on the board. Light bulb moment, with a small tipped soldering iron and magnifying glass I reworked the solder joints on the chip now work first time every time back in the key.

Hope this helps.
