Oil Burner Housing Lock size

[JJ800]

Hi I'm new here so hopefully I have posted this in the correct section. I have oil fired central heating with small galvanized housing outside which houses the boiler and oil burner. The oil delivery man had to bleed the system last time and I lost the key so we forced the door off. I'm looking to replace the lock and key with a new one so can anyone link me to one online or tell me what size I need. I think its a cylinder type lock about a 20mm long barrel.
any input would be appreciated.
Thanks
JJ

Hello JJ. What make is the oil boiler? Not the burner, but the actual boiler, as often the boiler house is same maker and the lock can be bought from them.
