Hi, my wife drives (still) a Ford KA MKII With this unfortunately the transponder in the flipkey is defective. At Ford there is only the complete flipkey for 170 Euro plus control and the plastic key without radio for 70 Euro plus control. Currently my wife has both keys on the key ring and starts the car with the plastic key. Now the car is to be sold and I have little desire to present to the new owner such a key chaos, just makes also nen schlec hten EIndruck. How can I repair the key as cheaply as possible? I cut the transponder out of the spare key at a certain Seat and then installed it in an increased key. This is what I have in mind this time. However, the financial effort would only be to get a transponder quite high, 70 Euro plus tax to buy a key that I then cut. Does anyone have a better idea? I’m afraid you can’t use the transponder. Greetings, isn’t it?
