When I ride my 2003 cbr f4i I unhook my key from my keychain and use it on my bike. Once I return I usually hook it back to my keychain for safekeeping. After 2 and a half years of doing this with no spare my luck ran out. My key fell down an elevator shaft! I tied a string to my cell phone and sent it under the elevator while recording a video and I can see it sitting on the bottom. I called my landlord and he told me it would cost $150 to get the elevator guy to come take it out. I've been reading around and I know that I would have to take the ignition out of the bike and take it to a locksmith to get a new key made with the key code. I am not very good with tools so that is not an option for me, and neither is getting it towed there since I am at work during the day and cannot really take a day off for the next few weeks. I was able to get access to my rear seat lock and was able to find 2 alphnumeric key codes on it. One is 4 digits and it goes alphabet-number-number-alphabet and the other is 3 digits and it goes number-alphabet-alphabet. Could someone tell me if that would be the same key code to use to get a key made for the ignition? Any other advice would be helpful. Thanks in advance.
