Lost Key

[Casstronaut]

I have using a Golden Motor 36V12AH lithium battery to power a solar bike with my students.
Over the summer I misplaced my key. There is no key number ID on the lock, and Golden Motor seems unable to help find e a replaceement key.
Any suggestions would be grateful...

Hi Casstronaut andto the forum.

If you have lost both keys and cannot obtain a replacement key you may need to purchase a complete keyswitch assembly.

The keyswitch can be accessed by removing the four screws holding the end cover in place:


You may need a high wattage soldering iron to unsolder the wires from the old switch and resolder them to the new one.
Although, if you don't have access to a heavy duty soldering iron and the switches are identical, it might be possible to remove the contact cover complete with the wires and carefully swap it with the one on the new switch.

Try pulling the old switch apart first to see if it can be removed easily without damaging the cover. If you break the old switch trying to remove the contact cover I would suggest that you leave the new switch intact and find a suitable soldering iron (or someone with a soldering iron who can do the soldering for you) instead.



Before you refit the end cover onto the battery, make sure that the cables are not under strain and pulling on the switch contact cover like they are in the above photo.

When I lost my key I disassembled the lock mechanism.
and removed all the tumblers.

The dome shaped piece pointing down in the photo below
is a thin cover, you can pop it out to get to the lock.

I had to drill the tumbler cover to remove them, but it was
not too bad.  Pay careful attention to how you disassembled it,
lots of one-way pieces.

Now the power switch is an "any key"
