It is even better, especially as I understand FOUR KEYS ARE SUPPLIED WITH EACH BATTERY, to take FAR better care of the said battery keys.....
On my batteries (2), I ONLY got two keys per battery! Still have both, and I have made two sets of keys for my bike, including the original alarm remote, and a copy which I made myself (dead easy!).
I am not saying how clever I am, because I see this as "normal practice" for keys, any keys for anything, car, house or e-bike.....
After I retired in 2006, I had a long holiday, but got bored, so in 2007 I worked as a locksmith for a company, learned a lot, but I found the work at best "Immoral". So after I had picked up all the tricks of the trade (bloody simple!), I resigned. But I still work for friends and family when needed......
You would be amazed just how many people lose keys to their property each and every day, or lock themselves out! And almost any idiot with a piece of plastic, can open the door in 10 seconds......it is worryingly easy!! I can literally, with both eyes closed, at 75, still open a door in less than 30 seconds......
