Security System locked up the Car?
 

Hi guys!
Another problem happened the other day. Came out to the car and the key would not turn.
(it wasnt the steering wheel lock) It wouldn't budge and the shifter button wouldn't unlock!
Got out and tried moving the car. Key would not even want to turn and shifter button locked up. I called for someone to pick me up. I finally grabbed(remembered) an uncoded key I keep in my wallet in case of lock out. Put it in and it turned. I didnt try to start, then put the real key back in and it all worked!
I think I remember going to the car and lifting the door handle and it not being open(from the keypad switch) My keypad is acting funny. Going to put a new battery in it. Half the time it doesn't seem to open everything.
The key locked again a couple days later(since changing keys) and I think I hit the door open button and it then turned.
Went to the manual and for an old fart like me, its confusing!!
Any input appreciated.
Thanks much to all!
Danny
