1998 Saab Bell will not stop dinging, even when key is removed.

Check leads are firmly connected on battery. New batteries have been known to be faulty. Needs power for locking door.

Check for play in ignition switch.If too much weight on keyring ignition switch may become damaged allowing key to be removed when switch is not actually fully in "off" position.

It sounds like it thinks the key is still in it all the time. Try turning the key forward to the on position, but not running, so the dinging stops. disconnect the battery. Remove the key completely and reconnect the battery.

your door switches are probably dirty spray them with wd40 then scrub them with a tooth brush

if the dinger is going crazy. just remove it. on most vehicles its underneath the dash on drivers side. that will fix it !

sounds like a new one on me ,unless you have picked up the wrong keys or someone has tried to break in or stuck them up with superglue

You need a door pin switch in the drivers door. It must have gone bad, and this is very common. Usually it is hard to find out what door it is that is causing it, but in your case with the dinging bell- it thinks the drivers door is open- thast why the dome light stays on. The door pin switch is a little sensor that is installed on the latch assembly with a wire going to it and it is supposed to sence if the door is open or closed and turn the dome light on/off. you have to remove the door pannel and reach back to the latch. They are VERY tricky to get out without taking the whole latch assembly out. The part shouldnt be that expensive though.

It may be trying to get your attention for an open door, trunk lid or other item requiring attention. Check your owner's manual for items that can cause it to chime.

Check your fuses. It's wierd but there is a certain fuse that blows and the chime is non stop!!

U will need to replace the low coolant sensor or try cleaning the one that is there now, they get coolant deposits on them and cause a false low coolant light/warning
