Most computers have to be flashed before, or after you install them, some local mobile locksmith's have the equipment.

SOURCE: DOOR WON'T OPEN FROM INSIDE OF NISSAN ALTIMA 2002 ON DRIVER'S SIDE

There is a cable that attaches to the inside door latch release handle. The plastic that retains this cable is most likely broken. I have seen this before. If the retainer is not holding the cable sheath correctly, the entire cable moves when the handle is pulled and does not release the door latch.

Remove the door panel and inspect this cable. You will see 2 cables (one is for the door lock). If the plastic is broken, you will need a new interior handle assembly.

Hope this is helpful!!

SOURCE: replacement of a head gasket on 2.5 liter nissan altima 2002

frajogag: First off, be aware that these bolts are "torque to yield" bolts (streach bolts). What this means is that instead of torqueing the head bolts to a specific torque specification, they are torqued down to a set spec and then tightened by rotating the bolts a certain angle, like 90 degrees. and all of them are turned the same amount.
This means that the shanks of the bolts must be checked to make sure they are not too thin (or the bolt has already stretched beyond limits and is prone to snap if used)
Here is how you check the bolts. Measure the bolt using a micrometer, at the base, or within the first 13mm from the end where it threads in. Then go to about 10mm before the threads end heading toward the top of the bolt. There should not be more than a 0.23mm (.0091 inch) or less difference or the bolt should be discarded.
Torque the bolts down to 98.1Nm ( 72.ft lb)
Looking at the head from the side, so you are looking at the full length from side to side, I will number the head bolts in this fashion.
#1 & 2 are directly in front of you and in the center of the cylinder head crossing it width wise.
#3&4 are to the left of #1&2, / #5&6 are to the right of #1&2
#7&8 are to the left of #3&4 / #9$10 are to the right of #5&6
Now, you have the sequence.
After the initial pull, back off all the bolts in the same sequence and then retorque them to 36 Nm ( 28 ft lb)
Using a torque angle wrench or having the ability to accurately judge turning angles. Rotate (clockwise) to a 75 degree angle. do this to all the bolts using the sequence I had provided.
Rotate the bolts (clockwise) 75 degrees again on all bolts in the same sequence. The proceedure is complete!

SOURCE: 2002 Nissan Altima Exterior Door Handle

I seriously doubt that supergluing or even epoxying a handle back will hold at all, or hold for more then few days.
I would only suggest doing the replacement yourself if you familiar with this type of work, or has the aptitude to figure out how to do it, and have the right tools because it is NOT trivial and a number of things can be done wrong, broken or scratched.
The handle itself cannot be replaced. The outside door handle assembly (which includes the handle, the bezel with all associated springs, plastic and metal hardware) has to be replaced. Besides junkyards, which is a long shot for number of reasons, the only place where the handle assembly can be bought is the dealer. And these handle assemblies are not cheap ether. The driver side handle on my 2002 Altima broke first. I paid $60.23+tax, and they had to order it. BEFORE anyone goes to the dealer I suggest to call first, and ask them if they have it in stock. Since door handles are sold painted they will ask you for your car's VIN number so that they match the paint color.
After you pick it up, the replacement will take about an hour (if you know what you doing). The inside door panel has to be removed, it is held in place by the inside door handle and the panel is attached by a number of clips, the handle assembly is attached to the door by three bolts, to remove which you will need a socket with extension. You will also need a good flashlight so you see what you are doing.
If you are familiar how to do this type of work and plan to keep the car for a while I strongly suggest buying a factory service manual on a CD (I bought mine on eBay for under $10). It is worth its price 1000s of times over, and makes almost ALL repair work SOOO much easier.751424a.jpg73e3811.jpgd240851.jpg

How to reset anti-theft on a 2000 alero


The security, antitheft or lock picture/icon is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well.

Car won't start anti-theft light is blinking


try reseting the computer by leaving the battery unhooked for about 30 min. if that doesnt work then it may be a clogged fuel filter or you could check the fuel shut off switch in the trunk behind the drivers trunk panel.

Replaced the fuel pump. the car starts, but won't stay running


The anti-theft system will keep the car from being driven, so I would start there. You may need to reset the anti-theft or check the ignition key for problems.
