I have an Omega Keyless Entry that is hooked up for lock, unlock, and trunk pop.
There is no additional output, is there anyway to hook it up so that the lights flash or the dome light illuminates when it is locked and unlocked.
It is not for me, it is for my girlfriend's mom's 97 Taurus Sedan. She wants some kind of notification that it locks and unlocks.

one quick easy way would be to use a couple of relays from the lock/unlock output from the alarm.. just wire it as you would a neg output light flash relay..

85 12v+

86 lock output from the alarm

30 to lights

87 12v+

do the same for the unlock.... this will give you one flash for each lock and unlock..

for illuminated entry you can get a timer and have a relay start it from the unlock output..

you may want to also put relays on the outputs from the alarm to step up the output.. they are usually like .500 amp out

Would I have to use any diodes, or would I not have to worry about the lights backfeeding into the locks?

that is the reason for the relays.. you have to get a monster diode for the doorlocks because of the current..
