I would have a dealer look at it those alarms are very complicated..
Hey i lost my keys and had to replace the ecu,transponder with keys and barrel which i got from a local toyota wrecker after hooking it all up, the car turns over but doesnt fire??then after 5 seconds(of turning over) there is 3 loud beeps from the security system..the light flashes every second or so but nothing random..it also beeps the same when the key is removed from the key hole..do i need the transponder key to open the door first???does the car need a master reset to reconsise the new parts??disconnecting the battery doesnt reset it....as its with the security system do i need an auto sparkie or need toyota to have a look??please help me..regards hayden
