Sega Cab Keys

[Acid King]

So what's with the Sega cab keys? I got a PM from thegreathopper wondering about the keys I have for sale in the trading forum and whether or not they will work with the locks on his Aero. Apparently, the locks on the Aero, Astro and New Astro are all similarly shaped. When I had to order replacement keys for my New Astro, there were two sets of keys and locks that look almost exactly the same, one numbered 5380 and one number 5375. The 5380 keys fit my locks while the 5375 do not, which would suggest maybe the 5375s are for an earlier cab. Is there anyone else with a Sega cab that has any input on this? Anyone with a 5375 key+lock combo in their cab?

I have just picked up an Aero city with no keys but the locks are marked 5253, An Aero table I have is marked 5380 on the keys and the barrel of the locks so It looks like I need 2 keys marked 5253.
