I changed the battery on my crx7 2010 mazda and now the raido won't come on, or the electrical door key don't work AC comes on everytime I start the car, why are these problems happening?
You need to reset your codes, that simple your paperwork in your glove box will have a special code, If you don't have this number just ring your dealer and he can advise you how to proceed, easy if you own it, not if it is stolen like it thinks it is

this is a common problem with only using a key fob to get in.you should use the key once in a while to keep it free and operational.
spray some W-D40 in the key hole let it sit for a little while the try to put the key in the door and turn it back and foward untill it starts to move this may take a few minutes or 15min to unlock it but alittle bit of patience and tired fingers and hands and you'll be in.(after you get the lock free try using the key more often to save your self the head ache down the road)

Hi,I would check the fusible links at the battery positive terminal.They look like normal wires but can burn out and leave the insulation intact.Try to stretch them,you will find the dead one.
