Hi guys,
I'm new to this forum and was hoping someone can help me out with a problem i'm having on my 2005 TSX Auto.

When I get out of my car and press the lock on the remote only the back doors lock. Both front doors don't lock. However, if i insert the key to lock then all doors lock and alarm is activated.

Also if all doors are locked and i use the remote to unlock then i get the same problem so only the back doors unlock. The only difference is, is that the front side lights flash twice and I hear a "ticking" sound three times coming from the engine somewhere.

Is this a faulty remote that needs to be reprogrammed or is this an ignition / lock / alarm problem ??

Thanks!

I searched the database, and there's no set fix for the issue. Here's a description of the system from the Acura Interactive Network that may assist in finding a solution:

The security alarm system is armed automatically after the doors, hood, and trunk are closed and locked. For the system to arm, the ignition switch must be off, the key must be removed, and the MICU must receive signals that the doors, hood, trunk are closed and locked. The alarm can be disarmed at any time by unlocking the driver's door with the key or pressing the UNLOCK button on the remote transmitter.

When everything is closed and locked, the only inputs that are grounded, and have 0 V, are the driver's door lock knob switch (LOCK position), and the integrated audio-HVAC display module. In other words, all of the other switches are open, and have about 0.8 V-5.0 V, including the key cylinder switches. The security indicator in the gauge control module begins to flash immediately after the vehicle is completely closed and locked, and 15 seconds later, the security system arms and the security indicator flashes on for a shorter amount of time than before. If the security indicator does not flash, the system is not arming. A beep sounds and parking lights flash to confirm the security alarm system is armed if the LOCK button is pressed a second time within 5 seconds.

If one of the switches is misadjusted or shorted internally, or there is a short in the circuit, the security system will not arm. As long as the control unit continues to receive a ground signal (0 V), it senses that the vehicle is not closed and locked, and the system will not arm. A switch that is slightly misadjusted can cause the alarm to sound for no apparent reason. In this case, a significant change in outside air temperature, the vibration of a passing truck, or someone bumping into the vehicle could cause the alarm to sound. There is no glass breakage or motion detector feature.

If anything is opened or improperly unlocked after the system is armed, the control unit receives a ground signal from that switch, and the 10 V reference drops to 0 V. If the integrated audio-HVAC display unit is disconnected, the input loses its ground, and the input voltage goes to 10 V. The system sounds the alarm when any of these occur:

A door or the trunk is forced open

A door is unlocked without using the key or the remote transmitter

The hood is opened

The audio-HVAC display unit is disconnected

The remote panic is operated

When the system sounds the alarm, the horns sound and the exterior lights flash for 2 minutes. The alarm can be stopped at any time by unlocking the driver's door with the key or by pressing any button on the remote transmitter.
