So, how does that lock fit the empeg when you put it in the sled?

I guess you could have it attached on a long retractable cable, so it's tied to something secure behind the dash, and can hang out the hole in the sled when you have your empeg inside for a software upgrade. Then when you bring it back out after the upgrade you put the lock in and slide it back into the sled. Is there a hole in the back of the sled to allow the lock to fit?
