This answer was rated:

how can i reset the vehicle immobilizer system in my 2011 frontier? thanks!

Jay :

Hello and thank you for using JustAnswer.com

Jay :

Please explain why it's active, and I will explain on how to get it out of lock mode

Customer:

i drained the battery really low with accessory lights left on overnight ...

Jay :

That is what you need to do to get it out of lock mode

Customer:

this doesn't work for me.

Jay :

Does the security light turn solid when you turn the key to the ON position?

Customer:

no, just blinks

Jay :

Double check please,

Customer:

ok will brb

Jay :

The light will either be ON

Jay :

or OFF

Jay :

with the key turned to the ON position

Customer:

no it definitely just blinks

Jay :

It can't blink when the key is turned to the ON position

Customer:

hmm. ok maybe i had it in the start position?

Customer:

let me check again

Jay :

The light is either off, or on when the key is turned to the ON position

Customer:

brb

Jay :

ok

Customer:

ok the key is in position "3" and the red security light is flashing!

Customer:

promise.

Jay :

Do you have remote start or anything installed?

Customer:

nothing aftermarket, just the accessory lights direct from the battery posts.

Jay :

Try this,

Jay :

This will do a hard reset on the truck

Customer:

k

Customer:

ok

Customer:

i'm in the truck now, btw

Jay :

Disconnect the negative battery cable for 10 mins

Customer:

i had the battery out all last night

Customer:

should i do it again?

Jay :

You want to only disconnect the negative battery cable for 10 mins

Customer:

ok

Jay :

Let me know how you make out

Customer:

wait that is it?

Customer:

just one step?

Jay :

yes

Jay :

Disconnecting the battery for 10 mins, that does a hard reset on the whole truck

Customer:

how exact does my timing need to be?

Jay :

I will explain on how to reprogram the windows cause they will need to be reprogramed also

Customer:

k

Jay :

You need to wait at least 10 mins, not any sooner

Customer:

but 11 is ok?

Jay :

yes, that is fine

Customer:

k

Customer:

do you think i tripped something by having the battery removed for an extended period of time?

Jay :

After you disconnected the battery, come back and I will explain on how to program the windows

Customer:

battery is disconnected.

Jay :

When the battery is low, you can run risk of having the keys loss there programming

Jay :

But not normally

Jay :

To program the windows auto up feature, this is what you need to do

Customer:

i think i did that .... ! it was super low(11.2 volts)

Jay :

First start with the windows all the way down

Customer:

i can't operate the windows

Customer:

ii have no power anywhere in the truck.

Jay :

I am telling you this now

Jay :

for later

Jay :

when you reconnect it

Customer:

ok ...

Customer:

right

Customer:

but even when its connected

Customer:

because of the immobilization

Jay :

Oh

Customer:

yeah

Customer:

the thing is totally dead

Customer:

no lights, blinkers, radio

Jay :

When you turn the key to the ON position does all the lights on the dash come on?

Customer:

none

Jay :

Oh

Customer:

just the immobilization light

Jay :

You tried jump starting the truck?

Customer:

yep

Customer:

with a fresh jump box

Jay :

You popped the main fusible link

Customer:

no response at all

Jay :

Get a flash light and look close on the positive battery terminal.

Customer:

is that in the main box under the hood?

Jay :

That is where the main fusible link is located.

Customer:

on the terminal itself. ...

Customer:

ok

Customer:

let me check

Jay :

It can be hard to see

Jay :

But if you have no power like your saying, then you have a blown main fusible link

Jay :

It's not the Immobilizer.

Customer:

well that one dash light flashes

Jay :

That is why the light is still blinking, it doesn't see the key is turned on

Customer:

how is it getting power though?

Customer:

i see four fuses, and they all appear to be intact ...

Jay :

1 second

Customer:

k

Jay :

I know they look intact.. they always do. Trying to get you another image

Customer:

k

Customer:

?it has been eleven mins. should i reconnect

Jay :

That is a picture of all the links location on the positive battery terminal

Customer:

reconnnected battery.

Customer:

thanks for the image

Customer:

i missed the two main ones up top

Customer:

the 140A fuse is clearly popped!

Jay :

If the link is blown, then disconnecting the battery is not going to help

Jay :

If it's popped that is your problem

Customer:

roger

Jay :

That main fusible link will need to be replaced

Customer:

you think then the key reset feature will need to be used ata all?

Jay :

This is only available from the dealer I am afraid

Customer:

can i pick that up at a regular auto parts

Customer:

ohh

Jay :

No

Customer:

really?

Customer:

damn

Jay :

sorry

Jay :

Yeah

Jay :

It's a dealer item only

Jay :

since it's 2011

Customer:

ok thanks. do you think they keys will need to be reprogrammed

Customer:

?

Jay :

to be honest, it may also even have to be ordered

Jay :

No, not likely

Customer:

oh no!!

Customer:

are these really rare parts?

Customer:

a 140 amp fuse is huge

Jay :

They are not rare

Customer:

how did i pop it?

Jay :

Something with the way you tried to jump start it

Jay :

That is the most common cause

Customer:

trying to jump?

Customer:

hmm

Customer:

leavig the box on too long?

Jay :

or backwards

Customer:

ohhhh

Customer:

i did do it backwards

Jay :

or connecting it improperly

Jay :

meaning

Customer:

because i've been doing a lot of electrical work inside

Customer:

and black is hot for houses

Jay :

When your hooking up jumper cables

Jay :

You want to hook up Positive first, then Negative

Jay :

If you do it the other way, you can cause a voltage surge also which can pop the link

Customer:

yeah probably backwards ...

Customer:

from the jump box

Jay :

Well that is what your truck is going to need t

Customer:

ok so once i replace that fuse, should i run any of these other diagnostics?

Jay :

You won't need to

Customer:

or you expect it to just work?

Jay :

You will need to program the windows

Jay :

like I outlined

Customer:

i think i cut you off ...

Customer:

can you please re-explain?

Jay :

Just remember to connect positive first, and then the negative battery cable

Customer:

roger.

Jay :

Ok,

Jay :

After you get the truck running again

Jay :

to program the auto up

Customer:

k

Jay :

for each window your programming

Customer:

k

Jay :

start with the window down

Jay :

Then hold the window switch up, so the window goes all the way up. Once it gets to the top and stops, continue to hold the switch for 5 more seconds

Customer:

k

Jay :

Then release it, and check operation

Customer:

k

Jay :

Do you have any more questions on this?

Customer:

not right now at least!

Customer:

thank you for your help.

Jay :

Your welcome, and thank you for using JustAnswer.com

Jay :

Thanks Jay!

Customer:

i was hoping i could avoid towing my truck to the dealership and reprogramming keys!

Jay :

You can, but you still need to go to the dealer to get the link

Customer:

right ....

Customer:

thanks again.

Jay :

Your welcome again.
