Genuine LiftMaster replacement parts for the EL2000 telephone entry system — the multi-board entry unit with display, 16-button keypad, camera lens and postal lock. Use the exploded diagram above to find the key number for the part you need, then click any part number in the tables below.
Two part numbers are stocked under different codes. The LED board is filed as 2B721 and the bypass board as SN1600341-K. Both are the correct parts.
Four boards, four jobs. The main board (041B0735) runs the unit, the input board (041B0736) takes the keypad and call button, the output board (041B0737) drives the relays, and the interconnect board (041B0997) links the door to the enclosure.
The housings and faceplates are discontinued in all three finishes, as is the display window gasket. Where a part number appears without a link, LiftMaster no longer supplies it.
Ref 22 is the EL25 key. The same replacement key fits the EL25 and the EL2000 lock kit.
