Door lock electric key switch
 
So I have had my bus about two weeks and have already managed to lock myself out of it.

It is equipped with a key lock for the front lever arm doors but none of the keys that came with the bus seem to work and the key/switch portion--sorry but I am not sure what the part is actually called and there is no part number on it--looks like it needs to be replaced but I had no luck finding one locally. I tried auto parts stores, a school bus repair and parts shop, and Tractor Supply Company.

It kind of looks like an ignition switch but it sends a signal to an actuator on the door open/close handle locking plate. I am including some pictures of the part below--and sorry for the crappy written discription.

The knurled silver end goes on the outside of the bus and is where the key is inserted. The back side with the spade style connectors had a black and pink wire connected that are then routed to the actuator on the door handle locking lever "thingie".

The threaded barrel is about 1" in diameter. There is also nothing mentioned about this part in the AmTran manual.

If it helps the bus is a 1999 International AmTran 3800

Anyone have any idea where I can buy this part? Online is fine.

Mine had one of those. I removed it and put a master lock combination box on the outside with two momentary on push buttons inside. One for open and one for close.

Thanks for the quick reply. I am not 100% clear on how the thing is even supposed to work normally. Is the key typically a two position key and when you turn it to the right the actuator on the door handle latch is moved to the up (unlocked) position so you can then pry the door open? Then once you have the door open you turn the key back to the left and remove it which then disengages the actuator allowing you to use the door handle from the inside normally?

I know that this is a silly question but the key location on my bus is about 2 feet away from the door so you couldn't hold the key in the turned position and open the door at the same time.


By the way...that is a really clever solution you came up with.

Mine is an electric door. Turn the key and hold one way and it opens. Turn the key and hold the other way and it closes.

I don’t have an electric lock as you describe, the locking mechanism I have is the electric actuator that opens and closes the door.

Oh. If you don’t have a multi-meter, buy one. It’s an important tool to have in your tool bag/box and will tell you exactly how your keyed switch works.

Ah. My door is manual with the traditional handle the driver swings out to open the door. I had originally planned to remove the door and handle and just install a traditional RV type door...but after using it I have grown kind of fond of it.

Mine's pneumatic. I've locked myself out twice, but the second time I did it, I used an ice scraper to push up the emergency lever. That master lock key box looks like a brilliant idea.

My biggest problem is that I have no idea what the part is called which makes doing a search for it fairly difficult. Pretty weird that it isn't listed in the manual from Am Tran.

Before looking for parts check that your getting 12v to the switch.

If so check the switch by disconnecting it from the wiring and using a continuity tester between the
terminal that would be 12v and the other terminals.

You should see changes in the connection between the terminal when you turn the key. If not replace the switch.

If the switch apears good and your gettimg 12v to it you may have a bad connection or short between your switch and the actuator, a bad ground from the actuator or a bad actuator.

If I understand what you have, you have a 1999 IHC chassis AmTran bus with a manual service door with a vandal lock on it. When you turn the key it energizes some sort of switch that pops up the service door lock and allows you to push the door open.

That switch looks like what IC is still using today to open and close the service door from outside.

Making it more difficult is no key that came with the bus will fit that key lock.

Fortunately for you, there were less than ten different lock sets ever used. Most fleets ordered at least all of their vandal locks to be keyed alike. Many even ordered their ignitions to be keyed alike.

You should be able to go to any locksmith and find a key that will operate that lock.
