Nissan vehicles can have two types of security system. They commonly have an alarm and an immobilizer system. The alarm provides visual and audible alarm signals when someone breaks in, or simply opens the doors or trunk when the system is enabled. Nissan systems are not motion detection types. The Nissan alarms aren't triggered by vehicle movement or vibration.

The immobilizer system functions through the use of a registered key. They are two distinct systems. Enable the alarm. Close all the windows; remove the key from the ignition switch; close and lock the trunk lid and all the doors. You can use the keychain remote control to set the alarm--just press the locked padlock icon.

Listen for the indicator that the doors are locked. The hazard lights will flash and the horn will sound. The system will arm itself 30 seconds after the locked padlock icon button is pressed. Or, disable the alarm by pressing the unlock button--the unlocked padlock icon--on the keychain remote.

The security system stays armed. I'd like to disable the system so that the car will start. How do I do this? To temporarily override the system, see these instructions.

A permanent bypass requires re-engineering the system because engine immobilizers these days rely on multiple electronic modules and chips, the very removal or modification of any one of which, or reconfiguration, will itself activate the immobilizer. These immobilizer systems are complex and nearly foolproof to all but highly trained electrical engineers and even they will have trouble due to the need for specialized components, programming and so forth.

Immobilizers are essentially undefeatable unless you want to spend many, many hours poring over circuit schematics to design a unique bypass strategy. The bottom line is, in your circumstances it will be vastly easier, more efficient, and less costly to simply fix the immobilizer system that you already have in place. Indeed, the Factory Service Manual has a diagnostic protocol to accomplish just that. To that end, if you request a system electrical diagnostic a certified Mechanic, dispatched by YourMechanic right to your location, will get this resolved for you.

The engine immobilizer is a security device. Use the information provided here in a legal and appropriate manner. The key is read by the computer and if it matches, it will enable all systems to start the car. If the key does not match, the car will only crank but not start. While taking the car to a dealership or locksmith is an option, it could get expensive because you are at their mercy.

When you insert the key, a coil near the ignition ring picks up the RFID signal from your key and sends it to an amplifier. The amplifier then decrypts it and sends it to the ECU. If the key code matches the stored values, the engine will start.

However its location under the dash means you will have to remove the entire dash pad. The procedure for reprogramming is similar, however you will have to short two wires on the OBDII port to perform a hand-shaking procedure between the ECUs to program new keys. This is where you need to get a programmer to connect the chip to your PC.

You can either buy a USB programmer from eBay or make your own to communicate to the serial port. The components required are fairly basic, three 4. If you do have problems reading and writing from the chip, you have to short the crystal on the board. PonyProg, a free serial device programmer was the software used to read information from the serial port and "dump" the EEPROM's contents. First go to setup under options. The content should appear as an array of HEX characters. Each key has a unique 8 digit HEX code.

There are also bits to indicate key count, enable programming mode and valet lockout. After a lot of experimentation, it was observed that there are three distinct keys. Each key is an 8 digit HEX value, repeated three times. It is split across two groups of four, but there is symmetry in their positioning within the dump. This must be zeroed as well. When reconnected to the car, the ECU will be in auto-programming mode and will accept new keys as per the procedure below:. Briefly insert any key into ignition lock cylinder and remove immediately.

The security light should illuminate and remain on. The Security light may blink indicating it has accepted the key. After seconds remove the first key from the ignition. Security light should remain on indicating you're still in programming mode. After seconds remove the second key from ignition. After security light goes off remove third key from ignition.

The security light should extinguish and then commence to blink regularly. If the security light does not stop blinking, that key is not programmed to the car. This procedure should work on many Toyota and Lexus vehicles from the 's to early 's.

Tip 2 months ago. Since you're already desoldering the chip it'd be much quicker and easier to just switch out the chip with the one thats already programmed to work with your key.

If the car will not start and the security light is blinking, this may be a sign there is a problem. The microchip in your primary key may be giving you trouble. Sometimes microchips will wear out, so try a spare key that has not been used as often. You can also reset the system by turning the ignition to the "On" position and waiting 15 minutes.

If the security light stops blinking, turn the key to the "Accessories" position, quickly to the "Off" position and then pull the key out of the ignition. Then turn the car on as you regularly would. Installing a relay system is also a possible solution, but should generally not be tried unless you have consulted an expert to help diagnose the problem.

Go to a dealer to ask for their opinion.

The only reason manufacturers started making these keys is to hold us hostage to the ridiculous prices they charge for something that costs them less than a dollar. Go on Youtube, and search transponder key bypass. There are kits you can install, or hacks you can do if you already have one working key with a chip in it.If the engine fails to start using a registered key for example, when interference is caused by another registered key, an automated toll road device or automatic payment device on the key ringrestart the engine using the following procedures.

Restart the engine while holding the device which may have caused the interference separate from the registered key. If the no start condition re-occurs, NISSAN recommends placing the registered key on a separate key ring to avoid interference from other devices. Operation is subject to the following two conditions; 1 This device may not cause harmful interference, and 2 this device must accept any interference received, including interference that may cause undesired operation of the device.

Every car needs a contexAnti-theft systems are designed to prevent your vehicle from being stolen. These systems are constantly evolving. An anti-theft system may also integrate a car alarm or it might be just an engine immobilizer. This may be for many reasons including a dead car battery that loses its key memory or a dead battery in your remote. It could also be that your immobilizer chip is damaged in your key or the car door lock is damaged.

Step 1: Check your key fob battery. Make sure the battery is installed correctly in your key fob. If the battery is correctly installed, replace it with a fresh battery and try again. Step 2: Check your door lock cylinder.

If your car has been damaged in an attempt to steal it or break into it, the anti-theft system may have been engaged. Check for damage to the lock cylinder itself or under the door handle where would-be thieves may have punched through with a screwdriver.

If the lock is damaged, try using the passenger side cylinder if your car has one. Step 3: Check that you are using the proper key to start your car. The key you are using may not have the chip required to start your car. Step 1: Check for the anti-theft light. Step 2: Turn the ignition to the "on" position. Insert the key into the ignition and turn it to the on position, which activates your accessories but not the engine.

Step 3: Check the anti-theft light again. Step 1: Insert your key in the lock on the door. Step 2: Turn the key. Hold the key in this position for 20 to 30 seconds. This lets the system know you have the correct key, and it can allow you to bypass the alarm system. Some vehicles recognize the key simply by turning the key back and forth in the door lock key cylinder. An anti-theft system that prevents your car from running properly is a nuisance, and while you may be thankful for it in the event of a crime, it is now causing you a great deal of inconvenience, which these steps have hopefully helped you resolve.
