Drilling out battery lock

[TForan]

I somehow misplaced the keys to my Biktrix battery. I have a spare one and was thinking of drilling out the lock. I've watched videos but I was wondering if there is anything unique about these kind of locks. Thanks !

I'm confused, you must be saying you have a spare lock? I thought at first you were saying you had a spare key. Locksmiths can pick just about anything in a couple of minutes. In fact you can buy a pick set on Ebay for less than $10. No idea how a Biktrix lock works, but these are not high security mechanisms.

I have a spare lock mechanism with keys. A locksmith is $75 , so I thought I could drill it out.

I'd spend the $75 on a locksmith and expense it under the heading "Education" instead of risking damage to the bike. One slip of the drill and that $75 you were trying to save will seem like chump change. Was the $75 estimate if you brought the bike to the locksmith's shop or an onsite visit? The latter sounds right for my area.

It has a single pin spring loaded at the rear of the lock. It really seems to be quite lightweight and will be fairly easy to drill.

Sounds like you were ready to go before asking.

Not really but having a new lock to look at helps to decide whether I want to try it.

Three seconds with a drill and it unlocked. Much ado about nothing ! Thanks for the help.

The battery lock on my Biktrix Juggernaut has fallen out and I need to get a replacement. How did you get a replacement battery lock for your Biktrix?

Any tips? What size drill bit? Drill in the centre? Does it just unlock when you have done it correctly?

Thanks in advance

I am a Locksmith and can offer this advise but the most important thing to remember is not to drill too deep or you may damage the lock actuator. Drill bit size depends on type of lock. Typically I would start with a 1/4". Sometimes the rotation of the drill bit will open the lock. Sometimes you have to fish out the debris and use a screwdriver to turn the core. I have seen a lot of locks damaged by amateurs that should have been left to a professional to open that resulted in higher costs of repair than if they had called a Locksmith in the first place.

Hi erider_61

I might be falling into the amateur category The lock is drilled but I still can't turn barrel. I gauged depth from new key and lock i have. What is the aim to remove all the pins, which I believe I have done?

Thanks

The pins are what prevent the cylinder from turning when locked. If those have all been removed, I have no idea why you couldn't turn the cylinder to unlock the lock.

If it is a pin tumbler lock it has 2 sets of pins and a spring per chamber. Often when drilling out the bottom pins the top ones will jam in the chamber preventing the cyl. from turning. This is where a locksmiths specialized tools come in handy. A hook pick can often unjam these pins or sometimes a slightly larger drill bit to open up the keyway some more.

Ok I have really screwed the pooch on this one. I drilled out the whole barrel after the barrel wouldn't turn hoping that once the spring that holds the battery locking mechanism was gone the mechanism would fall into the barrel. That hasn't happened . Think I am running out of options, I am sure a locksmith doesn't want to deal with this mess. Attachment shows lock type. Any last ideas? Thanks

Well that is a wafer lock(pic 1) which has the springs on the side of the wafers and would have been simple to pick open, but often becomes a problem when drilled. In (pic 2) the red arrow is pointing to the lock tab which is spring loaded. If you drill further through the lock keyway cyl you will drill off the actuater on the end of the cyl core that holds the spring and the lock should open. You are going to need a drill bit almost as large as the cyl. face in order to destoy all of the actuator.

Is that ramped strike spring loaded? Can you get a tiny screwdriver driven up against that ramp to force it down? Old house locks were as simple as wedging a credit card in against that ramped to push them in.

It is spring loaded but the end of the cyl plug prevents the actuator from being depressed when in the locked position.

Finally got it open. Thanks everyone for your help it is much appreciated.

If anyone reads this in the future and they are trying to drill out an Abus lock for Shimano Battery system than completely drill out the barrel which includes the spring and then ramp will fall into the chamber and battery can be removed and new lock fitted. I worked my way up to a 12.5mm drill bit before the barrel was completely gone.
