Jeff, The reason that most trunk-mount radios are locked is to prevent theft and tampering. The lock has no electrical function. You will need the ubiquitous #2135 key to unlock your Mitrek drawer. You definitely want to open up the radio before applying power to it, so that you can ascertain if the channel elements are in place, and what optional components are installed. Since Motorola shipped two keys with every radio sold, most radio shops will have a drawer full of #2135 keys. If you ask, you will likely get one or two free.

Hi, I know it's a dumb question, but after scouring the internet for info, I find everything about locks and replacement keys for Motorolas and other radios, but I still don't know what locking the Mitrek actually does. Does it kill all power to the radio, or disable certain functions? I'm asking because I just acquired a low-band Mitrek that I need to power up and verify its working condition. It doesn't have a control head, so I need to use the front panel pins, but if the radio is locked, I may end up getting nowhere and still not know if it's either the radio that is bad, it is locked out, or I wired it wrong. This is the first Mitrek I've had. Thanks for any help. Jeff KP3FT
