98 corolla- alarm, immobiliser and central locking dont work when pressing remote. Car starts when immobiliser disarmed with plug. It factory fitted Toyota alarm/immobiliser system. Changed batteries of remotes and car but still doesnt work. How can i get it working like normal with remote? Please help. Thanks.

You need to have the alarm module scanned by the dealer.

Lock and unlock the drivers door with th key.

depending on the type of security system, it is sometimes necessary to re-sync the keyfob to the car after a flat battery on the car or the fob.
this is normally just a matter of turning the key to the IGN position and pressing the button on the key fob. you may have to hold the button for a second or two but this will normally re-sync the system.

if it does not work then you will have to sent more detailed information on the security system. ie factory fitted or aftermarket system with make and type (normally found on the siren unit under the bonnet.

hope this helps

factory fitted alarm/immobiliser,resetable with doorlock/key.not all fitted with interior sensors(different markets)to test lock (with drivers door window open)leave car for about a min then try opening door using inside door handle (pull lever).horn will sound intermitantly....to reset shut door and press lock button on remote.

open door. when alarm goes off put key in ignition and turn it on start car. this should disarm the factory alarm.

My KZTE Double Cab Bakkie (Utlity vehicle) comes with a Factory fitted central locking system
Yesterday the Remote would not un-lock the vehicle. The battery in the remote has been checked and seems ti be OK. I managed to open the vehicle (coat hanger through rubber on door method), when opening teh door the alarm went off (hooter etc). I placed the remote in the de-activating housing but it did not de-activate the alarm. I am now driving around with the flashers going for 20 seconds or so every time I open a door, but teh vehicle drives (I took out the hooter fuse to keep my sanity)..

Please help

Simple thing to do is have your coils checked.. You should have spark if they are good.. If you still dont then disconnect battery at least 20 - 25 mins see if it resets ecm and alarm. May begin to work properly again..

If im not mistaken,your car should have an alarm reset/override.Below the steering column,on the dash should be a slot where you put your remote transmitter to deactivate the alarm.If that works,you then need to have your remote checked and coded by a vw dealer.Good luck.

if not the key probably the reciever in the ignition switch for the immobilizer transponder

with any BMW they have their problems, one is the central locking/immobilizer, the central locking is linked into the immobilizer and vice versa, the immobilizer takes it signal to disarm from the central locking and the ignition key ring. (chip in the key) if one of these starts to play up it has loads of consequences this being one of them. they all need to work together for the system to work properly. you would need to read the alarm and immobiliser codes using an ob2 tool that can detect them, and find the fault some problems it can be the drivers door sensor in the lock this is the main door as its drivers side and it controls all other doors on the central locking. if the switch is worn in any of it movements the system will not know the door has been opened, this does not work on the interior light as that is a switch in the door frame. the door lock is lock unlock and deadlock with key with remote fob its also arm disarm alarm and immobiliser. i have seen in some models there is a sensor auto lock so when you walk away with the key the doors lock automatically all lease parts work together. any one having a problem can cause no signal to be sent to the others in the system to start engine .
