Transponder key

I had my 2005 Lincoln ls 3.9 for almost a year. I lost my spare keys and was wondering if anyone knew how to program a new key without have a diagnostic computer to hook up. Locksmiths are almost as bad as the dealer for their prices. I have one original key and I don't want that one to die out on me

You can't.
I have a $400+ scan tool that can do it, but I assume that you would count that as "diagnostic computer."

The thing is my obd2 port won't power up the scan tool

Assuming that the port is the problem, and not the tool, it will have to be fixed first.

maybe the reason dealers and locksmiths charge so much is because they need to recoup the cost of thousands of dollars in tools that you don't have...



I also don't really think its too overpriced to pay somebody $40 to use a very expensive computer you don't have.

this is also why you should always have three different keys, that way if you ever lose one, you still have to keys that you can use to program your own with...

The dealer only gave me 1 key. I see all these post about being able to program 1 key on the Internet but I'm not 100% sure they will work

I think my dealer installed the gps thing on my car and used the power supply from my obd2 port to power it.

YOU can not program any keys with only one key


some places that sell keys (hardware store) can clone your key if you only have one OR a dealer or good scan tool can add additional keys no matter how many you have.


you can only program more keys if you have two.
