mobile mini container guard

[Gaspare Lioni1947]

I have 6 mobile mini container guard locks. I am trying to rekey them all the same. (4 have keys and 2 do not). Picking the non-keyed locks was very easy however disassembly of the plug to reassign the pins has proven frustrating. I cannot seem to find any way to release the tumbler mechanism from the cylinder. I commonly work with Kwikset, Schlage,Canan, Master and many automotive and industrial locks . This is my first work with the mobile mini container guard lock.
Anyone with an insight as to how to remove the tumbler from the cylinder to replace the pins would be appreciated.

Can you post a pic, even the same lock on eBay would be helpful

So if this is your lock, have you loosened the screw on the back of your lock?

Then you need to use a pin punch to drive out the roll pin connecting the locking bolt from the back of the KIK cylinder.

Once the locking bolt is removed from the back of the KIK cylinder, then you will need to shim the cylinder and use a follower with a hollow end to fit over the end of the KIK cylinder. The shim will help bridge the gaps between the KIK cylinder and the follower.

Some models require using needle-nose pliers to remove a pin that keeps the plug from rotating more than 90 degrees in the housing, too.

I have forgotten exactly which brand uses the following but be careful.

To add to all that info, some of these have cutouts on the side of the plug itself. I guess to save brass or weight. But if you try to remove the plug sideways, top pins can fall into the cutouts and lock up everything. Also the key might not release the plug to come out. If yours is a 5 pin key there may be a 6th top pin that drops into a groove on the plug to limit the turn distance and keep the plug from coming out. Check the bottom of the cylinder to see how many holes there are. If you cannot reach the 6th pin, you might have to drill a1/16" hole up from the bottom just to clear the bottom of the milled groove. You can push this 6th pin up through the hole on the bottom. Use a very thin wire or flat pick that can bypass the key wards. Use the shim to pick as the key may block the probe for the 6th pin. Keep the shim GWiens2001 suggested using all the way through to the front of the lock and leave it in to assist replacing the plug.

These are definitely a PIA the first time you try one. I hope your Mini Mobile is not like this one.

Sorry but I cannot figure out how to post any pics of the "MOBILE MINI GUARD LOCK" . And yes, the lock is completely disassembled except for removal of the cylinder from the plug so I can rekey it!
I cannot find any release mechanism for the cylinder at all.
If I can figure out how to post the PICS, I'll gladly send them along.
Thank you all for your replies.

Email me the pics and I'll post them here. Squelchtone at gmail

Read my reply above. It tells you what to do. Punch the roll pin that attaches the locking bolt to the back of the KIK cylinder...

Some pics of the cylinder

As I previously stated in my post, the "Mini Mobile Container Guard" lock has been completely disassembled except for the tumbler mechanism from the interior of the plug! Yes, the roll pin that attaches the locking bolt to the back of the cylinder has been removed. (See "https://imgur.com/a/ySmXTkc"). The tumbler apparently has some type of locking mechanism preventing the cylinder from being removed from the plug and it also restricts the rotation of the cylinder beyond 90° clockwise within the plug chamber. I also tried to insert a .002 shim between the cylinder and the plug before "picking" to possibly allow whatever type of locking mechanism is employed to retain the cylinder within the plug to facilitate the release of the cylinder to no avail. (Tolerances would not allow the shim stock to pass between the cylinder and the plug due to a restriction of sorts).
I'm sure there is someone out there who has rekeyed this type of locking mechanism.

It gets better. I carried the mechanism to a local locksmith and in a somewhat disgusted voice, informed me that these locks could not be rekeyed! But if I was willing to pay for his services, he would try to rekey the lock for me!

I am retired and still operate a small machine shop and I would never think of charging someone who was asking my help in learning a new task or skill. I guess I'm different.

Thanks to all for your help,
Gaspare

That lock was never intended to be taken apart but I've done a couple.

Gaspare, reread my previous post. The pin that blocks your shim fits in a milled groove in the plug and allows the plug to turn 90 degrees when the key is inserted or picked. It CANNOT be reached without drilling a very small hole up from the bottom, through the bottom of the keyway or drilling down from the top to remove the spring and pin. if you drill down from the top, the hole can be later plugged to keep the pin and spring in. If you are worried about just where the pin is, the shim stops at the back edge. Use the shim to mark the edge of the pin on top of the cylinder.

Make a plug follower to support the shim before trying to remove the plug.

If you get that far, don't forget to use the shim to prevent all the top pins from falling into the groove while removing the plug. They will lock up everything.

My past experiences are screaming at you!
