Keyless entry flashing dash lights!

[Subaru Group]

Hello, I replaced a failing alternator, and upon reconnecting the battery,
the keyless entry started flashing my marker lights and dash lights. It did
this 30 times and then paused for about 10 seconds. Then it started again.
Is it trying to program itself?? I finally unplugged the keyless entry
module! Any help on this is greatly appreciated!

Makes sense that if the alternator was replaced, then the power was off for
all components no?

In that case, you probably have to go through the sequence to get your car
to recognize the key pattern on your keyless entry unit. The pattern is
held in memory of the car, but is hard coded in the unit. You gotta tell
your car which key unit is yours.

Consult your manual for the sequence, I think its "open door" "switch
ignition on and off 15 times in less than 40 seconds" then "press keyless
entry unit button". Or something like that.
