How do you pop out the ignition of a 87 ford taurus with no key?

we're looking into buying an '87 ford taurus wagon that's sitting in a junk yard but the owner of the yard doesn't have the key. to have a locksmith come out is more money than we would like to gamble with because we don't even know if it runs, so we were wondering if it's possible to take the ignition to him and save some money.
