Nissan Repair: 2002 Nissan Altima 2.5S Repair, nissan altima, key fobs


Question
I recently bought a 2002 Nissan Altima 2.5S. I bought the car without the remote control lock (keyfob) system. I observe that the security indicator by the VIN is blinking which means if I am able to buy the remote lock control, it will work. where can I get the nissan remote lock control and how can I identify the one for my car?
QUESTION 2:
The radio, audio and timer display light was working until two days ago when it suddenly stop working. What can be responsible for this? Although the radio and the audio systems are still working, the time is no longer showing; the stereo signal and the tuning dials is no longer showing. I can not identify the tuned stations. Please how can I get it fixed, please help me.
I have this Hanes service Manual, I have read it but there is no similar problem in the manual.

QUESTION 3:

The drivers side window is no longer responding to control, it does not wind up or wind down when you operate the switch, the automatic control switch. The other paeesnger windows are working normally.Only the driver's side that refuses to move up or down.
Please help me.
In my location, we do not have experienced and knowledgeable Nissan Mechanic or Technician. Iam afraid to release my car to them because 2002 - 2009 Nissan Altima models have a lot of electronics and the majority of the Mechanics in my location are very ignorant of auto-electronics. please help me.
Iam waiting for your answers.

Answer
the key fobs are available from the dealer, then you are sure you are getting the proper one.  the radio is a sealed unit that is not serviceable, you can get an exchange unit through the dealer aswell
