old simple car alarms

[jkmadsci]

I have several old car remote alarm transmitters. Does anyone know what frequency these transmitters used.

Also is there a fcc website page that allows me to search by fcc id?
I searched , but I couldnt find any data.

for example fcc id bgapro2t or elv55aal767

Your location is very important. Regulations are different around the world, and if we assume that your device meets the local regulations, this narrows it down a lot. (Previous answer gives you good input if you're in Bangalore; is this helpful?)

Best place to express your location is in your User Profile so we don't have to keep asking.

the old car alarms operate at 301 mhz.
Here is the link to a page that has info based on fcc id
