Lost key for ABUS Bosch Downtube Battery Lock – need help removing battery

Hi,

I’ve lost the key to my ABUS Bosch Downtube Battery Lock on my Cube e-MTB and I just need to get the battery off the bike. I’m fine with breaking the lock since I’ll be buying a new one anyway.

I’ve already removed the cover. Is drilling out the lock cylinder my best option at this point? I’ve read that you need to drill straight through the barrel all the way, working up in drill bit size until the locking tab drops and releases the battery. Is that correct, and what size drill bit would you recommend?

Thanks
