The IM508 immobilizer is supposed to retrieve many PIN codes that the MaxiSys platforms generally can't do . Diagnostics capability only = MK808 though.
I wanted to be able to try IM508 new out of the box a few times without having to register and update the product immediately , but unlike my Elite that let me use up to 10 times before registering , my IM 508 won't let me in diagnostics to scan a single vehicle.
I am trying to find out if all the new IM508 are like that , or maybe someone was real careful to keep product looking as new , used it 10 times and returned it for a refund, since the original yellow security tape appeared to have been cut before.
The thing boots up fine and checked serial number was never registered before, so I have no reason to believe it won't work if I wait to register device later when I finally get a newer high security type key my Elite can't do. . Since I only bought the IM 508 to supplement my MS908 Elite key programming, so I don't need it for day to day diagnostics.
Autel don't tell you is that for some vehicle key programming requires an active update subscription and internet connection to Autel server to do keys of some cars, so after your 12 month update period is over , so is the ability to do the keys of those type of cars unless you keep update current. I don't know what cars require the internet connection and whether or not I will need to use my phone as a Hot Spot for the IM508 to do it's thing if I'm working mobile.
