The alarm will only arm or disarm if we hold the remote under the steering wheel close to the dash.

buy the correct keys, per maker toyota's instructions
guessing never works,
ask the seller of the new remote why it does not work
they will answer. ASK THEM.

hi

it sounds like the remote control module is faulty or the wires have come off

you will have to remove the cover under the steering wheel and get a copy of the alarm wiring diagram and follow the central locking wires test them to make sure they are working and still connected

time consuming but it has to be done to find the fault

Your alarm is is in valet. to take the alarm out of valet with the remote: open any door. Press lock, unlock, lock. The LED should be off now. Close the door and lock the doors with remote. The alarm should chirp to confirm that it is armed.
OR
Turn the key on then off. Within ten seconds press and release the valet switch. The LED should be off now. Close the door and lock the vehicle with the remote. The alarm should chirp to confirm that it is armed.

anti theft light should blink every few seconds.

try disconnecting the battery for 15 minutes.

Anti-Theft-Perimeter The perimeter anti-theft system consists of the following components:

• anti-theft indicator (THEFT)
• remote anti-theft personality (RAP) module
• hood switch
• keyless entry remote transmitter
• deck lid ajar switch

NOTE: The remote entry features will not function when the ignition switch is in the RUN or ACC position.
Up to four keyless entry remote transmitters (15K601) can be programmed at one time.
The keyless entry remote transmitters :

• Are programmable.
• Must be set at the same time.
• House four buttons.
• House three buttons (Mexico Anti-Theft System only).

Programming
Refer to Section 501-14B.
Inputs and Outputs
The remote anti-theft personality (RAP) module receives input from the following components for anti-theft operation:

• Hood switch.
• Deck lid ajar switch.
• Keyless entry remote transmitter.
• Power door lock switches (LH and RH).
• Door courtesy input.

The RAP module distributes output to the following for the anti-theft system:

• Power door unlock relay.
• Power door lock relay.
• Liftgate unlock relay (Wagon)
• Park lamps relay.
• HORN relay.
• Dome lamp.
• THEFT indicator.
• Deck lid release.

Arming
The anti-theft system can be armed if:

• The ignition switch is in the OFF position.
• The panic alarm is off.
• All doors are closed.

NOTE: If a door is open, the anti-theft system is prearmed and waiting for all the doors to be closed. The THEFT indicator will remain illuminated for up to 30 minutes waiting for all the doors to be closed. If a door remains open after 30 minutes, the THEFT indicator will turn off and the system will return to a disarmed state. After all doors are closed and the 30 second prearm (continuous THEFT indicator illumination) is complete, the system is armed.
NOTE: If the theft LED does not flash after 30 seconds, check the LED FLASH PID to see if the feature is enabled.
The anti-theft system will be armed when the lock button on the keyless entry remote transmitter is pressed, all doors are closed and 30 seconds have elapsed.
When the system is armed, the THEFT indicator will flash quickly until the system is triggered or disarmed.
Disarming
NOTE: Using a key in a door lock cylinder to unlock is not a valid method of disarming the anti-theft system.
Untriggered System
NOTE: If the driver arms the system and remains in the vehicle, an untriggered system can be disarmed by turning the ignition switch to the ON position.
An untriggered alarm system can be disarmed by pressing the unlock button on the keyless entry remote transmitter.
Triggered System
NOTE: If the hood or trunk are open when the system is armed, it must be closed and opened again before it can trigger an alarm.
An armed anti-theft system can be triggered by the following conditions:
The deck lid door, liftgate, hood or any door is opened using a key, inside door handle, hood release, etc.

• The keyless entry remote transmitter can activate a panic alarm which is similar to the anti-theft alarm, but does not cause the THEFT indicator to flash.

A triggered alarm system can be disarmed by:

• Pressing the unlock or panic button on the keyless entry remote transmitter.
• Turning the ignition switch to the ON position.

Alarm State When Battery Power Is Cycled
When the RAP module is supplied power the first time at the vehicle assembly plant, the system will be in the disarmed state. The RAP module will remember whether it is armed, disarmed or triggered in its non-volatile memory. When the battery positive cable is removed and then reconnected, the system will return to the state it was in just before the battery was disconnected. If the system is in any prearm state, then the system will return to a disarmed state when the battery is disconnected and then reconnected.

If your alarm is going off intermittently:

It could be the shock sensor; usually located around the steering column under the dash. It is a small black box with two small lights ( one red, one green) and a philips screw used to adjust the sensitivity. Counter clockwise reduces the sensitivity.

It could be an open trigger: door, trunk, or hood pin. If you have a pin in the trunk or under the hood that was added by the installer, they sometimes can be inadvertently bent downward by loading the trunk or, some guy changing your oil. If that is the case, just bend them back upwards until they make contact with the hood/trunk lid when closed and you receive one chirp when arming the system.

Here is a quick way to determine what exactly is causing the alarm to trigger:
After the alarm triggers, disarm the alarm and pay close attention to the LED light. One flash is the shock sensor. Two flashes is the hood/trunk pin. Three flashes is the door trigger.

factory alarm or a add on alarm

the location of the kill switch was chosen by the monkey who fitted it,so anybodies guess....under the dash by the side of the steering column is as good as any....

Hey, I bought my 1995 Nissan Maxima GLE brand new back in July 1994 with factory installed alarm, it just doen't make any sound when you arm or disarm it with remote. The only way you can tell whether it is armed or disarmed is from the lever position of your doors and the blinking red light under the dash. Only the newer versions of Nissan/Infiniti's has the "Audio/Silent" mode button on the remote which allows you to activate/deactivate you car alarm with an audiable sound or no sound at all. No worry, there is nothing wrong with your remote or car alarm.

The ignition lock anti-theft switch (19A438) detects if the ignition key cylinder is broken or "slam pulled" during a theft. The ignition lock anti-theft switch is always monitored by the remote anti-theft personality (RAP) module. This allows the alarm system to be triggered in the case that the ignition lock anti-theft switch detects tampering of the ignition key cylinder (even in the event that the alarm is not active at the time).
Refer to the Section 501-14B for more details on the keyless entry remote transmitter (15K601).
The door open warning lamp switch (14018) communicates to the RAP module through the generic electronic module (GEM). This input to the RAP will cause the anti-theft alarm to be sounded if the anti-theft alarm was armed.
The door disarm switches are assembled into both LH and RH lock sets. The door disarm switch must be triggered before the mechanical lock unlocks. This is to prevent the anti-theft alarm from activating when it should have been disarmed.
The RAP module controls the anti-theft system and is the brains of the keyless entry system. The RAP module communicates with the GEM to request that the interior lights be turned ON/OFF with use of the keyless entry remote transmitter, and the GEM communicates to the RAP to inform when the door is opened. Refer to Section 418-00 for inter-module communication.
The RAP module has three wire connectors attached to it:

• The antenna for the keyless entry remote transmitter.
• 26 circuit connector (C256).
• 22 circuit connector (C257).

In addition to the perimeter alarm that uses the door open warning lamp switch, the RAP module also uses the ignition lock anti-theft switch and the autolock/relock feature to prevent theft of the vehicle. For a full description of the autolock/relock system, refer to Section 501-14B .
The THEFT LED is found on the instrument panel between the tachometer scale and the needle pivot point. The LED is illuminated during prearming and flashes when armed or triggered.
Prearming and Arming the System
The system can be armed if:

• The ignition is OFF.
• The PANIC alarm is OFF.
• All doors are closed.

There are two ways to prearm the system:

• Press the LOCK button on the transmitter.
• Open a door, press the power door lock button and close the door.

After 30 seconds the system will be armed and the theft indicator in the cluster will flash every two seconds.
Disarming an Untriggered System
An armed system will be disarmed with one of these valid actions:

1. Pressing the UNLOCK button on the transmitter.

1. Placing a key in the door and turning to UNLOCK.

1. Turning the key to RUN or ACC.

The anti-theft alarm can be triggered by the following conditions:

• The ignition cylinder is damaged with or without the RAP being armed.
• A door is opened without disarming the armed RAP module.

The remote transmitter can activate a panic alarm which is similar to an anti-theft alarm, but does not deactivate the starter or cause the theft indicator to flash.
Disarming a Triggered System
If the system has been triggered, (the horn honks, the lights flash, and an external starter interrupt relay is engaged), the system can be disarmed by:

1. Pressing the UNLOCK or PANIC button on the transmitter.

1. Putting a key in the door and unlocking the door.

1. Turning the ignition to RUN/ACC (Turning the key to RUN/ACC will not disarm an alarm that has been triggered by the ignition lock anti-theft switch.).

Under the dash, Your installer that worked on your Cobra should have put an valet button under the dash, It is a small round Black button, Ok with the driver door open,,put your key in the ignition and go to the on position, Locate the black button before you do this, once the ignition is on hold the black button down for 3 seconds hit it once more and then turn the ignition off, the light should start flashing again and the chirp for arm and disarm with work again, What you have going on is called Valet mode which is designed to put the alarm side of the system to sleep which can happen from accidentally bumping it.

Hope this was helpful.

That Crazy Install Guy.
