You can go to your local Library, they usually have automotive manuals (Chiltons, Haynes, etc.) that you can check out. Or, you can purchase these at your local auto parts store $10-$20. They are very useful to have on hand and provide decent photos.

SOURCE: Is there a way that I can reprogram a key fob

yes u can and here is the procedure.
1. Close and lock all doors with the driver’s side power lock/unlock switch.

2. Insert key into ignition and remove it from the ignition key cylinder at least six times within 10 seconds. Your Hazard
Lamps will flash if you have performed this step successfully. NOTE: Withdraw key completely from ignition cylinder
each time. If this procedure is performed too fast, system will not enter programming mode.

3. Insert key into the ignition cylinder and turn to the ACC position.

4. Within 5 seconds, push ANY button on the remote transmitter. Your Hazard Lamps should flash. NOTE: Do not press
the button more than one time in the above step. If the button is pressed more than one time, the programming
procedure will not be successful.


5. If there are any remaining transmitters (including the old ones), unlock then lock all doors using the driver’s side
power lock/unlock switch and within 5 seconds, push ANY button on the next remote. Your Hazard Lamps should
flash. Repeat this step for each transmitter (including any existing transmitters).

6. Turn the key to the OFF position, remove keys from the ignition, unlock doors using the driver’s side power lock/unlock switch and open the driver side door.

My 2003 Altima 2.5s makes a humming type (vibration?)sound.


I have a 2003 Nissan Altima making a humming sound towards the front of the motor at idle in Park.

Not sure if alternator or compressor.

Not rattle from timing cover has to be something Nissan already denies.

My timing chain sounds loose. can it be adjusted or should it be replaced? 2003 nissan altima 2.0


If it is running loose for a long time and is worn then should be replaced as soon as
But if the tensioner has come loose which it shouldn't have then an inspection of the links will further tell you if it should be replaced.There are ways to inspect the timing chain.This is a rough guide.

Timing Chain and Sprockets Cleaning and Inspection
  1. Clean the components with cleaning solvent.
    Caution Wear safety glasses in order to avoid eye damage.

  2. Dry the components with compressed air.

  3. Inspect the timing chain for binding or wear.

  4. Inspect the camshaft and crankshaft sprockets for:
    • Worn teeth (1)
    • Damaged teeth (2)
    • Chipped teeth (3)
    • Worn valleys between the sprocket teeth

  5. Inspect the crankshaft sprocket keyway for wear.
  6. Inspect the crankshaft sprocket oil pump drive splines for wear.

  7. Inspect the chain guide (232) for the following conditions:
    • Loose metal inserts (1)
    • Cracking (2) in the chain contact area
    • Excessive grooves (3) in the chain contact area Grooves 1 mm (0.040 in) or less in depth are to be considered normal wear.

I have a 2003 Nissan Altima. Do I have a timing Chain or Belt. How long does the timing chain last? I have 195,000 miles on my car.


Timing chain. Normally they will last for at least 150,000 miles or longer. If it becomes noisy or car is hard to start, backfires, or performance is sub-par have it checked.

Timing belt replacement millage


The Nissan Altima does not use a timing belt, it uses a chain driven camshaft, timing chains have no set mileage and should last the life of the engine.
