Hi-
Yes, all say HD74. I?ve never actually used the bike so I?m little unfamiliar with the locking positions. So the lock was in the far right position, which I?ve now learned is the on position. The key made one click to the left and stopped. Now it won?t turn any further right or left. I charged the battery but the green light on the green light on the battery itself doesn?t illuminate. So I plugged into the USB port on the LED screen and it will illuminate for a second when I press the mode button but that?s it, it goes back out. Am I doing something wrong.

I have a 2020 Rad Rover Step Through. Unfortunately, I lost the key and Rad has them on backorder. The bike is locked and I bought four universal keys and they don?t work. If someone out there has a lock with key code F503, I would be more than willing to compensate you for the trouble of making a duplicate for me. Thank you.

Thanks for the responses. The bike I have is a 2020 Rad Rover Step Through. The key code is F503. That is a very good idea to reach out to someone with the same key code and ask for help.

Thanks for responding. I have bought four of those keys that you mentioned. None of them worked. No locksmith wants to mess with it. So frustrating. I understand the supply chain but Rad can order a box of keys and ship them via FedEx to the US. Customer is so bad now. You?re lucky if they get back to you.

I have a Rad Rover Step Thru that I bought in 2020. Unfortunately I lost my keys during a move. Rads key are back ordered and have no idea when they will be getting them in. I bought one of those Rad Universal keys on eBay but it doesn?t turn. Does anyone have an extra F503. Or could point me in the right direction in order to purchase a universal key. Thanks.
