It would probably be cheaper to fit a 12V solenoid and have done with it.

Most solenoids take about 30A to pull them in and a bit less to hold them so you'd be looking at a 0.4 Ohm resistor to drop the voltage. Becauses of the current involved, that resistor would need a power rating of around 200W which won't come cheap.

Choice of 6 there, ranging from about £21 upwards. In other words, about 50% more than a new 12V solenoid!
