Fire! 1991 Ford Explorer keyless

I just checked the relays and only one of them shows 87a.  The other has two 87 pins.  The one with two 87 pins is a 12 volt / 30 amp relay that i bought at Autozone.  I went and bought a second one that only had two 87 pins and had the same problem.  Am I using the wrong relays?  What is the difference between using a relay with two 87 pins and a relay with an 87 and 87a?

The relays with two 87's The 87's are ouputs switched on when the relay coil is charged The relay with 87 and 87a The 87a is switched on when the coil isn't charged and the 87 is switched on when the coil is charged 87a is switched off when the coil is charged https://www.the12volt.com/relays/relays.asp
