Hi, Please can somebody help me? earlier today i was trying to change the pin on my alarm and just when i thought i had figured it out and finally cracked it i tried to start the engine to test and the doors locked and the new code did not work.I decided to give up and try another day but then as i was about to turn the engine off the alarm went off. Now everytime i get in the car the standard seat alarm goes off after about 15 seconds even if i am driving down the road the only way i have found is to leave the door open when i start the engine. I could really do with some help as i can not seem to solve the problem even any suggestions on how to turn the standard seat alarm off would be great. hope you can help dan
