You may need a shop manual to get the testing procedures. You need to know if the ignition module is getting power and a signal from the cam and crank sensors.

SOURCE: security light stays on

First place to check would be a fuse.  See if there is one labled security or alarm.  If there is try changing that.

Yes there are struts on the front and shocks on the back. 2 of each. They are around $50-100 for the fronts. $30-100 for the rears depending if the car has air ride or not.

SOURCE: 1994 buick lesabre heater core removal

The heater core is located under the dash, in the center. The container holding the core looks like a black plastic box. Remove the ash tray for easier access. You may have to also remove some other covers under the dash. You must first drain the radiator then you have to disconnect the hoses. There are two hoses connected to nipples of the heater core that go thru the center of the firewall. Remove the screws that hold on the cover to the heater core. Then you should be able to get the old one out. There might be a couple of other minor steps but I'm sure you can figure them out. For re-installation just go in reverse order to put it all back together.

Transmission fluid

When I changed the transmission oil on my 88 Buick lesabre limited I took 6 qts of Dextron VI, and it is also wise to change the transmission filter. U can purchase the transmission filter kit from any auto parts store, not neccessarily the dealer. This is the best change for the vehicle.

1995 buick lesabre limited, cranks but wont start...what should i do?

May be fuel related or ignition related:

Fuel: Obtain a can of "starting fluid" from an auto supply store. Spray directly into air intake for two seconds. If car "kicks" and trieds to start, then the problem is fuel-related. If you spray more, then it may start.
Could be: Fuel filter or fuel pump.

Ignition: Remove a sparkplug cable and lay it down on a metal part of the engine. Have someone crank the starter while you look for a spark from the cable end to the engine. If no spark, it could be several things:
distributor rotor, distributor cracked and/or wet on the inside, ignition coil.
