Hello, I already looked at the appropriate topics here. Now to the case of my wife: She had bought a Ka used (EZ 97). The locks (doors and trunk) have a different key than the Zundschloss (was that changed? The red master key was only for the doors).. Of each she had 2 keys. She had always used the red master key (doors) and a black with red triangle (twisted lock). In short: She has lost them. Now she still has the replacement locks. l: 2 black with red triangle. Also here one for the doors and one for ́s ignition lock. My questions: The master key was apparently no longer for the WFS. So even if she had the still and the others would have lost, you could not program with it. Is it enough for the door locks to take a blank without a transponder? You only need it for the ignition lock, right? To the ignition key: Rohling with transponder probably costs about 40 euros. What costs the Progr ammierung bei Ford? Or are there other service providers? Possibly room Duisburg and surroundings. I am grateful for all the tips. Greetings Markus
