My car needed another key. The stealership quoted me >$400 for it. I took it as a personal insult and did the research and ordered an OBD device and also discovered you can order replacement keys on aliexpress, and they'll even cut them for you with a good picture of your existing key. It was actually a fun project and very satisfying when I was able to successfully program and link the RFID chip to the ECU to start the engine.
May not be feasible with more locked-down modern cars which I wouldn't touch with a ten-foot pole, but I was able to fix it for about $150, not including my time of course. But I have the OBD device to use next time now as well.
eBay key fob (new) + local locksmith, easy and no insults!
What's your plan for the future? I have an old car, but I know it won't last forever.
But with regard to a car, I don't know. I'll just do the best I can when the time comes. I'm hopeful there'll be options available or where I can cut antennas or whatever.
I bought a kit off of amazon "simple key" that included a programmer and a key with rfid chip. I think about $80.
You plugged the standalone dongle in the OBD2 port, did a procedure and it would take a few minutes and you would get an "original" key.
(The programmer said it was then locked to that VIN)
They key blank provided needed to get cut (did it at home depot).
I could then get additional rfid blanks for $7 and cut and program them.
Once you had two original keys, you could do the "DIY programming" method to make keys 3 and up.
The DIY method was something like "insert key 1, wait 3 seconds, remove, insert key 2 wait 3 seconds remove, insert new key, wait for something, remove" and you would get key 3, 4 ...
There were similar but separate ford procedures for programming the buttons on fobs to lock/unlock doors, etc
The mechanical parts of a car haven't changed much in the last 25 years, and are easy to understand just by watching a few YouTube videos.
The electronics have certainly gotten more complex, but if you can understand basic computer networking and low voltage electronics it's still quite simple.
If you are interested in learning how to fix your own car, there is a great guy who runs an auto repair business on YouTube and his tagline is: "Remember folks If I can do it, you can do it."
The other reason i did it is because the dealership and other shops quoted me over 10 times the cost of parts, and I literally did not have the money to take them up should i have wanted to. Car maintenance is expensive, _especially_ at the dealership.
