1999 altima keyless entry programming

I'm having problems programming a new keyless entry I purchased for my 1999 Nissan Altima. The FCC Id on the back is the same as my current remote and I've gone through the following steps:

1) locking the car from the interior using the switch

2) inserting and removing the key from the cylinder 6 times within 5 seconds.

3) turning the key to the acc position

4) pressing the button once on my keyless remote

5) removing the key

The only problem I can think of is that my car has an alarm and it in some way could be interfering with the programming. When I turn the key to ACC the alarm disarms regardless of whether I perform step 2 the hazards flash twice.

Can anyone help??

bring it to the dealership and they'll do it for around 30 bucks

try searching in this forum under Frontier. I found some good instructions to program and they worked!

I am having same programming problem with my 99 Altima.I took to local dealership and they were unable to program.They checked remote and said was good and the correct one.
Does anyone have additional ideas.
