Key Gone? Pull the Plug, Turn the Cam, Open the Door
A bell plug puller is the dent-puller of the locksmith trade. You bite a self-tapping screw into the plug, seat the bell over the face of the lock, then wind the nut so the plug draws straight out of the cylinder. The core comes away, you turn the cam, and the door opens. This Lokko set gives you the bell, a protective door plate and thirty screws in three sizes, and you drive it with the wrench already in your bag.
Watch the pull, step by step
This cut-away shows the Lokko bell puller at work inside the lock, from the first bite to an open door. The video in the gallery above shows the same pull on a real door.
- Bite the plug. Drive a self-tapping screw into the keyway so it cuts its own thread.
- Seat the bell. Slide the Lokko bell over the screw head and rest it on the door plate.
- Wind the nut. Turn the nut with your wrench and the plug draws out into the bell.
- Lift it away. Take the bell off the door. The pulled plug comes away inside it.
- Turn the cam. Reach through the empty cylinder and turn the cam to pull the latch back.
- Open the door. The latch clears the frame and the door swings open. Fit the new cylinder.
On a real door: before the pull and after it


What a bell plug puller does on a job
Picking and decoding come first when they make sense. Some jobs do not stay there: a seized mechanism, a damaged keyway, a failed rim or mortise cylinder, a stubborn Euro profile cylinder, or simply no usable key and a customer who needs the door open now. A bell plug puller changes the problem. You anchor over the cylinder face and put the pull through the plug itself, so the plug draws forward, clears the housing and the failed core comes out. The cylinder becomes the replacement part once you are through, and the door around it stays tidy.
Anchor over the face
The bell sits across the lock face on the door plate and keeps the pull centered, so the force goes into the plug and not into the door.
Bite, then pull
A self-tapping screw cuts its own thread into the plug, then the nut winds the plug straight out of the cylinder.
Turn and open
With the core gone, you reach the cam through the empty cylinder, throw the latch and move straight on to a fresh cylinder.
The working parts, without paying twice for the wrench
Most locksmiths already carry a good wrench or socket set, so this set leaves the spanner out and puts the money into the parts that do the pulling. The bell does the work, the door plate protects the finish around the cylinder, and the screws are the bite point. Everything packs into the storage tube so it rides in the van without rattling loose.
The puller is the tool, the screws are the fuel
A bell puller only works when a fresh screw gets a firm bite in the plug. Worn or stripped screws slip under load, so the screws are the part that runs down with use. A pack of Lokko self-tapping pull screws restocks the same three color-coded sizes, made in Germany with a SIT20 drive that takes a TORX20 bit, so the next plug comes out as cleanly as the first.
The cylinders a bell pull suits best
This earns its place on the trade side of the kit: controlled emergency access when saving the cylinder is no longer the priority. It suits compatible exposed or flush rim, mortise, profile, round and oval cylinders, where the plug face is accessible for a centered pull. Recessed, guarded, interchangeable-core and anti-pull cylinders call for a different plan, so read the lock before you commit to the pull.
Mobile locksmith callouts
For locks that are failed, seized, damaged or no longer worth fighting with non-destructive methods.
Rim, mortise and Euro
For compatible American rim and mortise cylinders plus Euro profile cylinders, where a clean pull beats chewing up the door.
Emergency access kits
For responders and tradespeople who want a compact entry option with screws and a plate already packed.

Questions buyers usually ask
What is a bell plug puller for?
It opens a locked door when picking or decoding is not an option. You bite a screw into the plug, seat the bell over the lock face, wind the nut to draw the plug out, then turn the cam to open the door. The cylinder is replaced after the pull.
Does it come with a wrench?
This set leaves the wrench out so you can use the one you already carry on the puller nut. If you want a dedicated cam turner and a second plate in one case, choose the Lokko Complete Set.
Will it work on American cylinder locks?
Yes, when the cylinder suits the pulling method. Bell pullers are used on compatible round and profile cylinders, including many US rim and mortise jobs. For recessed, shielded or interchangeable-core locksets, plan a different method.
How many pulls do the screws give me?
The set includes 30 self-tapping screws, ten in each of the three gauges. Screws wear with use, so keep a pack of Lokko pull-screw refills in the bag before the tube runs thin.
What else should I bring on the job?
Bring your driver with a TORX20 bit for the screws, the wrench you use on the puller nut, a tool to turn the cam, and a replacement cylinder.
How do I keep the door looking good?
Seat the bell squarely on the door plate before you wind. The plate and the bell spread the force around the cylinder, which keeps the work far cleaner than drilling or prying.
Pull the plug, open the door, fit the new cylinder
The Lokko bell plug puller set gives you a controlled pull with the parts that matter and none you already own. Add a pack of spare screws and it is ready for the next callout.
