your also suppose to hit door lock 2x before start and if alarm still goes off problem with fob or your aftermarket alarm programming

How old is the battery inside the remote? If that doesn't work you can try disconnecting the battery for 5-10 minutes and see if resetting the system will help. After that you may want to call it and send it in for repair.

BAD FOB?
or battery weak in fob?. replace them?
always have 2 fobs, so you can isolate problems and not get stranded.

is running engine charge lamp out?

or the button on the fob, panic, is bad,
to prove this take the battery out of FOB in use
and use the spare fob with fresh battery.
this proves its the fob, see how?

no,,,, the panic and the door open buttons all use the same
fob battery. try that, remove the battery see all buttons go dead.???
bingo... so the switch is all gunked up, (split cola, sweat.???)
the car came with 2 fobs. use the other fob.
lost it. get a new one, never run a car with 1 fob. bad idea.

btw, if id sold you this, car, the panic would be hacked, i kill them all.
when tripped, the panic my car, requires entry and key on,.
a royal pain that is. dog barking , babies crying, all that....

Here's some info as it sound like the theft deterrent is armed.

Reset Procedure

NOTE: This information applies to a Vehicle Theft Security System (VTSS) that was armed when the battery was disconnected and reconnected.

When the armed VTSS senses that the battery has been disconnected and reconnected, it enters its power-up mode. In the power-up mode the alarm system remains armed following a battery failure or disconnect. If the VTSS was armed prior to a battery disconnect or failure, the system will have to be actively or passively disarmed following a battery reconnection.

The power-up mode will also apply if the battery goes dead while the system is armed and battery jump-starting is attempted. The engine no-run feature will prevent the engine from starting until the alarm system has been actively or passively disarmed.

Passive disarming of the Vehicle Theft Security System (VTSS) occurs when the vehicle is unlocked using the key to unlock either front door or the liftgate. Active disarming of the VTSS occurs when the vehicle is unlocked by depressing the Unlock button of the Remote Keyless Entry (RKE) transmitter.

Once the alarm has been activated (horn sounding, lights flashing, and the engine no-run feature), either disarming method will deactivate the alarm.

Depressing the Panic button (if equipped) on the RKE transmitter will also disarm the VTSS, but the horn will sound and the lights will flash for about three minutes as part of the Panic feature. The horn and lights can be stopped by pressing any of the RKE transmitter's buttons or driving the vehicle above 15 mph.

dont you have the alarm key fob? if so that will reset it. just press unlock. If you dont an dits not a OEM Acura alarm you will need to find who makes it and get a new key fob, or have a shop that does alarms to disconnect it.

your battery is probably to low to start the car

the alarm may be in "stolen" mode already. what you can do is that you can switch the key into ON position and open the hood, remove the negative terminal from the battery and reconnect after two minutes. this will give the alarm time to reboot and recognized that you have the key to this vehicle.
