How do i find a key for my linksys router?

Try the following procedure on a computer that's directly connected to one of the router ports with an ethernet cable. This procedure will not work if you're connected wirelessly. Open a web browser, such as Internet Explorer, and type in http:192.168.1.1. A window should pop up asking for a user name and a password. Don't enter a user name and type admin for the password. Hit ok. The router setup screen should come up. Click on the Wireless tab and then the Wireless Security sub-tab. You should be able to see your present wireless network security key on this screen. You can also use this screen to change the key if you want.

If you want to make some changes first select the security mode you want to use. I believe WPA gives better security but I've had some trouble using it on older computers. I use WEP. I've been able to get this encryption scheme to work with all of my computers. Next select the type of encryption. I like 128 bit 26 hex digits. Next enter a pass phrase and hit generate. The pass phrase is like a password. It should now generate four 26 character keys made up of various letters and numbers. Write down the first key and make sure you've checked the 1 box for default transmit key. Save your setting and exit. You wireless network is now secure. If you try to connect to it using a wireless device you will be prompted for a security key. Depending on the operating system you're running, you may just be able to enter the pass phrase or you may need to enter the 26 character key you wrote down. You should only have to do this once for each of your wireless devices. After the first time they connect to the secured network they should automatically remember the security code. I hope this advice helps you out.
