How do I get a key for my '90?

[mrnickleye]

I just ran into this same problem for a customer's car last month.

The valet key is missing some cut on it.

You can take the car to the locksmith and have a hatch key made without removing the lock.

I did that on my 1990 Plymouth Sundance. He took the key and stuck it into the trunk lock, turned it both ways, pulled it out, and using some VERY powerful magnifying glasses to see, cut it from the tiny marks left on the key.
