Same issue Remove hood latch assembly (3-10mm bolts), and disconnect the alarm harness. If the radiator was replaced they probably damaged the hood latch anti-theft mechanism. Very common problem on this make/model/year. Easiest thing is to Remove hood latch mechanism, disconnect anti-theft harness, and reinstall the hood latch. You will have no anti-theft alarm because it can’t complete the circuit but it shuts off the anti theft so you can start the car. If that isn’t the problem, ignition may not be reading key chip but since they pulled the radiator most likely it’s the hood latch. Easy fix.
Also, with these Acura’s, it takes time for the transmitter to recognize the key chip. Anytime you start it, you must turn key to position 2 and wait until green key stops flashing, then you can start. When green key flashes, you know it is trying to read chip in your key to verify car isn’t being stolen.
