Code P1610 Nissan Description

The P1610 Nissan code refers to the Lock Mode, which is a security system feature in Nissan vehicles. When this code is triggered, it means that the vehicle's immobilizer system has detected a problem and has entered a locked state to prevent the engine from starting. This can be due to issues with the key, the immobilizer system, or the electronic control module.

Tech Notes for P1610 Nissan

This code is usually triggered when a not registered or damaged key is used to start the engine. When the starting operation is carried out five or more times consecutively with the same unregistered key, the system will lock. If the problem occurs try disconnecting the car battery for about 30 minutes and then try starting the engine with a known registered key. If the problem persists you have to have the dealer erase the code and reprogram the keys again.

If problem persists after disconnecting the car battery, try the following:

ESCAPE FROM LOCK MODE
1. Turn ignition switch OFF.
2. Turn ignition switch ON with registered key. (Do not start engine.) Wait 5 seconds.
3. Return the key to OFF position.
4. Repeat steps 2 and 3 twice (total of three cycles).
5. Start the engine.

    Eu tenho que usar as chaves do carro para abrir o carro e fechar.

  • Had code P 1610 and P 1614 took the car to dealer. They try to reset the system but no luck. Even purchase a new key. The car is still lock down. They tried to re flash both the ecm and bcm

  • What model and year is your Nissan? I never seen the ECM and BCM program causing that problem. You may have a problem with the IMMU

  • Hello i have a 2005 Nissan 350z, when i put in the key, the car CRANKS but wont start, when i put in the key and try to start it, the NATS Alarm red light doesnt disappear..the red light stays ON.. After 20 attempts and 20 min unlocking the door, turning the key on and off the ignitation, etc, it will finaly recoginze the key and will start perfectly. On other days, the car will start perfectly and will disable the alarm all the time. On other days, i struggle trying to disable the alarm. What COULD this be?! Is it the Key or the NATS antenna amp , Body control module (BCM) or (IMMU) Engine Control Module (ECM??

  • Do you have another key? or have you try with another key? If you did try with another key and you still have the problem, then the problem is more than likely the NATS Antenna on the steering switch. I have never seen an BCM or EMC causing that type of problems.

  • Are there any more codes? Unfortunately the P1610 code only means that the system is lock, but it doesn't actually give you the cause of the problem. My only advice is to have the dealer reprogram the key with the Nissan CONSULT, instead of replacing more parts.

  • Unfortunately I don't much experience with the Navara, but the P1614 usually means that the key is either bad or has not be programmed or the there is a problem with the NATS system control unit

  • sir thank you for your reply. but i have important one question that if Nissan car key not programmed that could make car wont's crank ???? because engine doesn't cranks or this mean there's other issue by your experience ??? because someone told me if key not programmed may be reason doesn't cranks ?

  • Correct, if the engine is not cranking at all, then there must be something else. If the key is not programmed, the engine should at least crank but no start.

    You could have 2 problems, the no start problem and the problem with the keys.

    Common no start problems are starter or the starter connection, or problems with the ignition switch.

  • okay thank you so much sir for your help first step i will try to program with new key then i see if security red light after few seconds disappear or not if yes then i will check connectors for starter. but security red light must disappear after few seconds in goods condition right ?

  • Where can I find a 2001 Nissan Cefiro A33 immobilized?

  • The car model is Nissan Sentra 200, 2007 model

  • Do you have another key? Sounds like the key may be failing.

  • My 02 altima se cranks but won’t start. Has a P0507, P1610, P1612. My car is stuck in my garage. I have an original key and second chip key made. I disconnected the battery for 30 min. And reconnected it, still won’t start.

  • Have you tried escape from escape mode:

    ESCAPE FROM LOCK MODE
    1. Turn ignition switch OFF.
    2. Turn ignition switch ON with registered key. (Do not start engine.) Wait 5 seconds.
    3. Return the key to OFF position.
    4. Repeat steps 2 and 3 twice (total of three cycles).
    5. Start the engine.

    If that doesn't work, then you may have to have a locksmith or the dealer reprogram the key for you.

  • Yes, I did it and still won't start. Can I take it to my regular mechanic or a nissan dealership? That sucks I have to get it towed. I'm not sure what you mean locksmith, a regular key locksmith?

  • Most locksmiths have the tools to reprogram the key and they can go to your house, otherwise you have to fin a mechanic that have the special scanner to reprogram keys. Although there are other things that may cause the no start problem, since you have the P160 and P1612, reprogramming the key is definitely the first step.

  • I called a locksmith. He said my keys were fine. Now I have to tow it to my mechanic.

  • Hi, I have this same problem. Did you fix your car?

  • hey I have a 2015 Nissan rogue, the car is immobilized and won't start; the battery died and must've triggered it. I've tried to jump the car via bypassing the starter relay with a jumper wire and still doesn't run. I honestly don't want to bring the car to a dealer and spend triple digits for their service; on top of towing the vehicle there.

    I already tried the ignition method, doesn't work.

    I scanned the car and I only get a U1000 (miscommunication code) basically the security system is keeping the ECU from cranking the engine.

    help me out with another method of resetting the security system.

    thanks and much appreciated

  • Besides the instructions to escape from "Lock Mode" above, the only other thing you can try is disconnecting the car battery for about 30 minutes to reset the system. If that doesn't work, you could try with you local locksmith. Most locksmiths have the tools to reprogram or diagnose key problems.

  • check for corrosion on yout battery terminals. or like in my 01 pathfinder check then main fuse mine melted right down, so i rigged it up with a phone charger until i came up up with something better. been driving like rhst for 8 months.

  • Hello pls I have Nissan amada is not state I most grogram it before stating

  • What model and year is your vehicle? If the keys are OK and reprogrammed, then you may have a problem with the IMMU.

  • Hello, I've got the same problem moreover hazard light up and wiper still moves, I did program key In the way that you indicated, I guess it's not just programmed maybe PCM, so, kindly I need to advise.Wbr Sherif.

  • Hello i hav a 2016 nissan urvan nv350, it has a trouble code oF P1610 N P1612, but my key doesnt have any immobilizer chip, the van keeps on cranking to no avail it never started, any thoughta how to repair this?

  • As far as I know all the Nissan models have the Immobilizer System. If you get the codes, either you are using a non programmed key or you have a faulty key. After you have to clear the codes and reset the system to reprogram the key.

  • reemplace bcm por qué encendía y no daba arranque programe y quedó al 100

  • Gracias!!

  • I got a 02 Nissan Altima 2.5 immobilizer on I turned off switch underneath the dash on accident when I went to pull the hood latch it's a little green light when I try to turn after that it won't start I've done everything you've said in previous don't know what to do now

  • The switch and green light must be an aftermarket alarm. Nissan does no have a switch under the dash. Do you have a picture of the switch?
    Try locking and unlocking the driver door with the key. If that doesn't work, try disconnect and reconnecting the car battery to reset the alarm.

  • hello there....I got an issue with my Nissan atlas f24 year 2011...its not starting I got the DTC code p1614 chain of immu key and p1610 lock mode...the truck is not starting...can you help me please??

  • hello can you tell me how to clear the code and reset the key?? I have an autel maxicom mk 908pro as diagnostic tool??

  • Start by reprogramming all the keys to your Nissan. If you can't reprogram the keys, then you must replace the NATS antenna to fix the problem.

  • Hi I have a 2002 nissian pathfinder in lock mode is there anyway to over ride the lock mode system

  • No, unfortunately there is no way to do it.

  • So from my understanding if the battery is disconnected for so much time it should reset the whole system how true is that and how would one know if the system reset or not

  • if the battery is disconnected for so much time it should reset the whole system how true is that

    Yes, sometimes by disconnecting the car battery the lock mode will clear and the engine will start. There is no information about this procedure in the factory service manual, but we did it at our repair shop and it worked.

    how would one know if the system reset or not

    If the system resets, then the engine will start, otherwise you must have the dealer, or a locksmith try to clear the codes and reprogram the keys.

  • One more question is it possible for the dealership to just do away with the system cause I no longer want it on my car

  • No one can do it. The system is wired and programmed to the Engine Control Module, and Body Control Module.

  • So can I go to a dealership of any kind that sells Nissans and they can reprogram my key?

  • Any Nissan dealership will have the tool to reprogram the keys. Some locksmiths also have the tools to reprogram the keys.
