There should be an instruction in the car user
manual on how to program your remote in case the keyfob id is lost.
normally even if you didn’t change the remote battery
for longer period, the receiver module has the ability to store id wihout
losing it.
may be you remote is in off frequency i mean the
frequency shifted a bit when you placed new battery plus your hands effect as
you hold the fob. im assuming that your fob is not a pll based or saw type, its
made of LC circuit.to check if its LC based, you should see a variable
capacitor inside the fob. in this case, you need an rf spectrum analyzer to do
so which is not very common as this is very expensive equipment. this will tell
if the fob is ok meaning it transmit with data while pressing the button and if
the frequency shift a bit then trim to as close in the specs and the problem is
in the receiver side.
last try before you buy, press the fob as close
to receiver say a meter away, setting on the driver side while pressing the
button is ok, if no responce, try varying the variable cap at a precise
movement of up +/-15deg angle first then extend to full rotation if no responce
at all. hope this helps.
