All channels are locked out how do i un lock them

Do you mean network lock??

Here it is, straight from the manual:

clearing a locked-out frequency
To clear a locked-out frequency, select that frequency (see
“Reviewing Locked-Out Frequencies”), then press CL.
If all locked-out frequencies are cleared within a bank, No
Lockout appears.
clearing all locked-out frequencies in a search bank
1. Press SRCH.
2. Select the search bank in which you want to clear all
locked-out frequencies.
3. Press FUNC then press L/OUT. Lockout list appears.
4. Press FUNC then 6. Clear entire list ? Press 1 to clear all, any
other key aborts appears. Press 1 to clear all locked-out
frequencies. List cleared. appears for about 2 seconds.
Press any key other than 1 to cancel clear.

I hope this helps. If it does, please take a moment to give me a rating. A rating of "very helpful" would be greatly appreciated.

first do a factory reset (pin no 0000) and rescan once all channels are found wait for saving then exit to menu. Enter 1570 on remote and scroling down to emu and turn on usuing <> keys. Exit out and select sky sports 1 and wait for update. Oncee complete you should have all channels back.

Access your manual numbered channel mode so you can "step" through each channel manually. Make sure that each channel is NOT in L/O or locked out mode. If it is, use the key that un-locks that channel. Also, make sure the frequency is correctly entered for each channel in question.

Press and hold Vol-Down and Chan-Down for 8 seconds.

pro 97 locked up wont scan

Simple, some Radio Shack models respond to their preset lock out override control protocol. Try holding the lock out button and the scanner should override the lock out on the banks. If that doesn't work, you may need to un-lock them one by one, which may be time consuming. Or, you could reprogram the scanner all together.

Hope this helps!
