A home owner from Maryland says:
Greetings. I need two Crestline Door Key Cylinders to match the attached photos. Please let me know if you have these in stock, the cost, and how long it will take to get them.

Many thanks,

Thanks for posting, Alan. Could you remove your key cylinder from the door and see if it matches up to either our 40-123 or 40-129? One of these may be what you want, but take a look and see if the dimensions match your key cylinder.
A handy person from Maryland says:
The bottom one looks right but I have removed the key cylinder and here is a photo so you can help me to confirm which one works...

Thank you! They both look similar, but I can't say for sure without knowing more precise measurements. I can't really tell what size yours is based on that ruler. Carefully go over the dimensions we show for each part and see which is closer to your measurements.
