Nissan Repair: keyless entry/clock fuse burn, keyless entry system, key fobs


Question
Hello, I have a 1996 infiniti i30.  I was testing my battery earlier today when I removed the (negetive) connection on the battery. Right afterwards, I noticed that my keyless entry remote which was working 20 minutes ago was no longer working, the alarm system was completely dis-functional, and my dashboard clock was completely blank.  I then checked my fuse box below my steering column and found a fuse labeled "7.5", I replaced the fuse with an intacted 7.5 spare and right after I put it in, it made a snapping sound and was burned.
I dont know what to do at all.  Can you help me?

Answer
George,

Check the master fuses at the positive terminal.  Then, check those under the hood that feed power to the clock and such.  To reprogram  the keyfob do the following:
1. Close all doors
2. Insert key into and remove it from ignition key cylinder more then six times within 10 seconds. (Hazard warning lamps will then flash twice.)
Note: Withdraw key completely from ignition key cylinder each time.
If Procedure is performed too fast, system will not enter registration mode.
3. Insert key into ignition key cylinder and turn to ACC position
4. Push any button on key fob once. (Hazard warning lamps will then flash twice.)
5. Do you want to enter any additional key fob id codes?  If No - Go to  step 9 , if Yes - Go on to next step (6)
Note: A maximum five ID codes can be entered. If more then five ID codes are entered, the oldest ID code will be erased.
6. Unlock the door, then lock again with lock/unlock switch driver side (in power window main switch).
Note: Operate this procedure even if the door is in an unlock state.
7. Push any button on key fob once. (Hazard warning lamp will then flash twice.)
At this time, The oldest ID code is erased and the new ID code is entered.
8. For additional key fobs do steps 6 thru 7.
9. Open driver side door. (END)
After entering ID code, check operation of remote keyless entry system.
