2001 maxima se Alarm system

[albert Johnson]

Has anyone disabled the alarm system on a 2001 maxima se so any
correct key will work with the car. My problem is the chip in the key
will go out or the key will get damaged and i'll have to pay a fortune
to get the correct key made.

I also want to add one of those devices that will open the door and
trunk and lock the door when the ignition is turned on.

Thanks in advance

Here's the "trick". The "chip" is imbeded in the key. Pry it out
carefully, then tape it to the steering column near the ignition lock. Then
get cheap duplicate keys made for everyday use.

Getting an extra key or two made through your dealer should be under $100
... why in the world would you want to disable a major feature that keeps
your beautiful car in your possession?!

When you purchased the car, you should have gotten 2 regular keys and 1
valet.. I wouldn't worry about the key getting damaged. My set has held up
exceedingly well.

Did you do that to your car???

How does it transmit a signal to the alarm.

I like your idea alot !!!!!!

Because all a car theif has to do is get the factory electrical
manual for your car and he/she can bypass the alarm system.
All alarm modules are in the same place in most cars of a model year.
Any changes will show in in the manual or the update of a manual

If i bypass the alarm and i get the stardard key , i can get all the
copies i want at a cheaper price!!

I didn't do it to mine, but I did it to a fleet of police cars, where they
required having more keys than the system allows in it's program.

No, it's not that simple of an anti-theft system...

The 20002001 Maxima uses a transponder system. Basically it is a
transponder computer than reads the "code" of the "chip" in the key. When
the key is inserted in the ignition switch, the transponder reads the code
through the antenna around the ignition switch. It then verifies it is an
authorized key, then sends what it read to the engine ECU, or computer. The
computer then compares this code to what has been programmed as authorized
key codes. If everything matches, it then allows the fuel and ignition
system to be turned on to start the car.

The thief would have to change the transponder, the ECU, and have a
programmed key that fits the key tumblers in order to start your car. He
gets 2 tries to get it right, if it fails to match on the third attempt, the
ECU locks out ANY attempt to start the car. Then everthing has to be
reprogrammed with the dealer's computer/diagnostic equipment. It's pretty
much 99% fool proof. I know of only one way to start the car without using
a properly programmed key in the ignition. And I can't achieve that without
first having a properly programmed key in the ignition within 5 seconds.

If you do tape the chip near the antenna, be aware that your insurance
company could deny a claim for a stolen car, as it's just like leaving the
key in the ignition. They based their theft rates on the fact that you have
this new type of anti-theft system.

I have seen the keys break the loop off the key. Usually it's when they are
on an oversized key ring and get dropped.

I'll have to try that if i can't get nissan to kill the alarm

Thanks alot !!!!

The only way i can see around is if a car thief takes a wire from
the battery to the starter after forcing the ignition lock to the "on"
position.

This should start the car cause it sounds like it is a glorified kill
switch

I still like the chip taped by the lock idea !!!!

Nissan can NOT legally modify the security system. You'll have to do it
yourself.

No, that will not trigger the ECU to fire the injectors and spark plugs, it
hasn't seen the "chip code" from the transponder. It will crank, just not
fire.

Here's the best analogy I can give you: Forcing the ignition lock and
jumping the starter has gotten you to DOS with a hardware patch, but you
can't run WINDOWS until the computer gets the password--it's programming.

Ahhhhh very well put. I understand fully now !!!

Can you please tell me your way of doing it??
I'm curios now. I told you my thoughts on it

[albert Johnson]

When i pull the chip out of the key, is it o.k to cut the leads
from the chip before i use electrical tape to tape the chip
to the underside of the steering column.?

Will this works on Fords too???

Thanks in advance !!

[Ronc303]

Cut the leads? There are NO leads on a Nissan key as it does not require
external power from a battery. The "chip" is just molded into the top of
the key. If you look close it is a retangle 1/8" x 1/4" near where the key
ring attaches.

The key must be taped near enough the "antenna" around the ignition switch
to register the key. I taped it directly under the ignition cylinder, under
the column could be too far away. If it is too far away, the car will
crank, but not start (or start and die immediately). You get 2 tries to be
close enough, then use a good key to start the car inbetween to more tries.
Do each test, then wait 30 seconds between tests.

I'm not familiar with the Ford Keys or their system. I'll look at my dad's
lincoln next week.

Thanks a lot for your help. I'm doing my research BEFORE i start
something the dealer might have to finish :) :)

Thanks again !!!

[Ronc303]

I used a needle to carefully ply the "chip" of of the key.
Then I superglued the chip on the underside of where the ignition key goes
in.

All done--now the chip is alway near the antenna and you can use any genetic
key, that is cut for the car, to start it.
