Lost Ignition Keys re 1984 Chaly CF50A

I own a very low mileage 1984 Chaly CF50A (bought new in Cyprus) which has been off road/garaged since 1992. I now want restore it to roadworthy condition but am stymied as a consequence of having either lost or misplaced the keys. Is it possible to source replacement keys without the hassle of having to change the ignition barrel or calling out a locksmith. I asked Honda UK for help, advising that I had the chassis and engine numbers but all they did was refer me to the local Honda dealer- so much for customer care/service! I've read somewhere that the key codes are detailed (sometimes) in the Owner's Manual. My version of the latter is in Chinese or Japanese so I cannot verify same. On the premise that I may have to replace the ignition barrel, is there a DIY method of removing the old barrel from its mounting? At first glance the task would seem to require a special technique and/or tool. I would appreciate any advice or responses from Club members on this post.

The barrell is simple to remove -------------if you've got the key!!!!!!!!! -------- not easy without it,without damaging things.
Do you have a number stamped on the lock?
A long shot ,but I have a quite a few period keys if you can find the key No.

Hi Chief!
Thanks very much for your reply. Unfortunately, no number on the ignition barrell. Are the keys coded alphabetically or numerically? I would like to trial the period keys if you would be so kind as to lend them to me for a short time. I would of course pay the postage involved. I fully appreciate that you may not wish to do so!

Regards.

Hi Glin,
Early ST's etc(70's) were 'H' series keys (H followed by 3 or 4 numbers). 2 different types of key groove also
Then I think 'T' series (+numbers), Both were all metal body keys,then plastic top keys appeared,but your testing my memory now.
Only the correct series of key will fit into the lock barrel so if you wanted to send me your lock I will probably have at least a key to insert if not one to turn lock,but you never know. You are welcome to the key if I have one,no problem.
PM me if you want my address,
Dave

Re my previous posts on subject and kind replies from Chief. I filed the problem under 'too difficult' but with the recent fine weather am moved to have another go. Went to to local Honda dealer (parts etc) who advised me to contact Express Locksmiths, Orpington, Kent with the key number which can be found on the rear of the ignition barrel. But still have the problem of freeing the ignition barrel from its seat. It is held firmly in place by 3 small metal lugs/wedges which do not respond to push/pull pressure. Is there a technique/knack or special tool required to release the barrel? All advice or guidance gratefully accepted.

I don'y know but this guy in the states can help for the Original keys I got mine with the locknumber.....
