I’ve brought a second hand bike and unfortunately the last owner has misplaced the keys for the removal of the battery , and ideas how to drill out the lock to replace it or how to remove the battery to replace the lock , I think it’s a abus smart lock

If this is a Trek bike, have the previous owner order a new set of keys. They will likely need the serial number and the registered name of the previous owner.

If you drill out the lock on your own you will likely need to order a new lock.

Get the help of a Trek dealer. They can verify the serial number and help with a new lock.
 
Which is why I earlier said:

OP does seem to be averse to getting help from a dealer. :rolleyes:

Would be interesting to know the provenance of the bike.
 
Exactly ! 😂😂😂😂, not everyone are scum bag robbers lol 😂
True. But you’re still without keys, a battery lock, new ownership registration, no history data, no warranty, no way to update the data, etc.

But you carry the fear of your motor being locked out and replacement battery and/or frame will be difficult.

There’s so many steps required when you purchase or sell a used e-bike.

of course, if it's like, missing key, missing charger, missing papers ....

Wow, it maybe reasonable to be somewhat skeptical but the speculation in the replies to this thread go way beyond what information the OP has posted!
We have effectively called him a thief.o_O

It seems like that. But there was a red flag for most of the regular members when they read the very first post, of a new member, who simply asked for help.

Selling or buying an e-bike can be slightly different than an analog, as you probably know. The Bosch motor has a security feature available to purchase ($10). If that is left activated when a Bosch powered e-bike changes hands, the motor becomes a brick and is likely digitally flagged.

There are a number of steps that a seller or purchaser needs to be aware of before an e-bike changes hands. Our expensive EMTB’s can be targets for opportunists. Sometimes a history of ownership and service is digitally available. Good info to have for either party.

The keyed lock is a pita in my opinion which is why I don’t remove the battery cover to often. But I keep the keys in a safe place.

With the greatest respect it is no surprise to me that a new member simply asked for help on this matter. Yes it may ring alarm bells but given that many owners have the ability to charge their bikes while garaged and thus not needing to remove the battery it does not seem unreasonable that battery lock keys could have gone missing and a bike was sold without them.
I feel the earlier responses suggesting taking it to a dealer were absolutely OK and maybe suggesting checking for a key number on the original invoice might also have been helpful. Had the OP then been evasive or raised excuses for doing that then maybe the speculation that followed might have been justified but the fact is those posts started within minutes of the original post and were without any basis that I can see! The 2nd response from the OP merely stated it was a Cube bike and therafter the replies he got continued to be less than helpful.
It may well be that we never hear anything more from this new member which might indicate that the speculative replies were justified or more likely, in my opinion, because of the unfriendly responses and trolling he got here.

Verbal diarrhea.

All of that is possible. I just hope the op finds a solution, even though some of the suggestions were given with limited, or unknown information. Even my spidey senses were somewhat activated.
 
All sorted now thanks , contacted the supplier with the serial number annd proof of ownership and getting one sent out , thanks for all the helpful comments from the few that were nice enough to take the time to help !
As I said on Tuesday @7.12am in post #4:

Cube dealer of course.
 
Good lesson for me anyways, I’m gonna check for those spare keys …just case.

I use to always ride with a spare key in my pack.…attached to a whistle. Never used or needed the key during a ride.

We have photographs of the ABUS key codes filed on computers which are regularly backed up. In any case, have deleted our Rail locks, and batteries are bolted in and only removed for occasional testing by our local Trek dealer.

That’s actually a good idea 👍🏻. I keep the ABUS cards in the corner of the tool drawer along with the keys attached right now. That’d be a great backup …along with other info on the bike.
Was that so you could whistle in key?
I can’t even spell violynne …what are you talking about?😄

Seriously though, we were always required to have a whistle hanging from our suspenders, which we were also required to wear. Compression bandage, analog watch, bucking cards, and usually a radio microphone attached to the suspenders for me. Felt like a costume after I dressed for work. And that’s just the top half. 🙄

After reading this, a certain Monty Python song comes to mind....
 
Suspenders! :love:
England and America, two countries divided by a common language.
Okay, okay 🤔 . Was there a song written about ‘suspenders’ by your rock’n’roll band called Monty Python?
Canada I think in this case but I'm sure he was not the lumberjack!;)
Did you just say “Lumberjack”?

I forgive you 🙏.
 
@Stihldog Monty Python was not a rock group but a comedy team, (properly known as "Monty Python's Flying Circus") with a prodigous output, much of it considered to be outright weird. But if you were the correct age group, laugh out loud funny. Here is the Lumberjack Song. Watch it right to the end to get a glimpse of their often surreal humour.
