Fix Dremel Lock Button Not Working

This situation with the Dremel lock is mostly caused by the excessive pressure from your grip, and you will have to modify your technique accordingly.

However, if the system is already damaged, you need to change the lock button on Dremel to get everything in order. 

Changing The Lock Button On Dremel

We have already mentioned that this is the only possible solution available for fixing the lock button. Similarly, it’s safe to say that this is the simplest option available.

To go ahead with this method, you need to collect a few tools, such as a 2.5mm screwdriver, a Torx screwdriver, and an opening tool for disassembling the Dremel.

Once you have the tools at hand, you can follow the instructions to change the lock button.

follow steps

  1. The first step is to take off the back case from your Dremel rotary tool. For this purpose, you must remove the housing cap, and it might need to be taken off by unscrewing. When the housing cap is off, unscrew the exposed collet nut and make sure to hold it down. In addition, you must hold the shaft lock button. As far as removing the collet nut is concerned, you might have to opt for an open-ended wrench that’s provided by Dremel in the package
  2. The second step is to remove the hanger from Dremel’s casing, and you will need to do it with your hands
  3. The third step is to take out the brush caps. The brush caps are installed on each side of the Dremel, and you can use the flathead screwdriver for this purpose. Also, keep in mind that the brush caps have a spring-loaded configuration, so be careful around them
  4. Now, take out your Trox screwdriver and use its tip to remove the screws. There are five 12.5mm screws that are meant to hold down the casing, and you must remove them all
  5. Then, with the help of a plastic opening tool, you can also take away the hard plastic threads but don’t apply too much pressure because it can damage the plastic threads
  6. Now, start removing the back casing but keep a light hand to ensure the components of your Dremel don’t fall out accidentally
  7. At this point, you have to inspect the shaft lock pin (yes, the lock button), and if it is not connecting with the rotary gear, it needs a replacement. You will also have to remove the damaged lock button and spring. Once the old components are out, install a new lock button to streamline the spring functions and make sure the lock button is connected to the rotary gear

These are all the steps needed to fix the lock button on your Dremel. So, try them out! Hopefully, you will not have a hard time trying to cycle through these errors, and it will barely take a few minutes.

Once you’re through with the adjustment, getting a responsible response from the system will be fairly easy. 

From here on out, you should just have to focus on keeping the unit in good shape. You might have to slightly modify your grip on the unit and make sure that the lock button doesn’t get engaged in the middle of normal operations.

Otherwise, you will run into more errors down the road and won’t be able to find your way through a fix. Hopefully, you will be sorted out right here and won’t have to deal with more complications.

Just make sure that the Dremel lock button is clean and never under pressure from your grip. A good thing to do here is to reach out to the lock experts.
