Keyless entry remote not working after changing the battery?
buy a new one from where you bought it from


before you spend too much money..check the solder and.try this.
On the inside of the keyless remotes, there are rubber buttons, those rubbers buttons are brushed with metal of some sort so that it reacts with the motherboard, when the remotes get older this metal wears off...so try this, it worked for me...

I superglued foil paper to the back of the button (the parts that touches the motherboard when pressed) and replaced the batteries... it worked like a charm, I used an awl and a hammer to make perfectly round piece of foil and just glued it onto the back of the button... i'd try this first before spending any real money
