CBP changes the keyset once a month, unless a radio is lost or stolen, then a new keyset is generated immediately. Users in the field request a rekey through OTAR on one of the NET channels. In the NY/NJ area, it's usually NET 1, 2 or 7. The KMC, or Key Management Center, will verify the radio and send the new keyset. The radio also keeps the last keyset as well for those users that don't update accordingly.
Additionally, if a radio is lost or stolen, the RID or Radio ID will be programmed into the KMC. When the radio is turned on and one of the NET channels is selected, the radio will auto affiliate. Then it becomes a useless brick
Also, CBP changed the ten-codes since Border Patrol is now part of CBP and had a different set of codes. There is a new consolidated list which I do not have, but 10-10 no longer means secure mode.
The only P25 NET channel in the NY/NJ area that I'm aware of is NET 2 and it's mixed-mode. All the rest are still analog. That's why you will hear DES-XL instead of DES-OFB on the NETs. All the ICE repeaters are P25 and DES-OFB. ICE still calls Charlie-100 on the NET channels for running datas and CBP has access to the ICE repeaters for joint operations.
