Hi All; As a progress for the previous posts: FOB/SKS Questions Finally! How to program a non-SKS key/fob. Detailed! I have bought 2 keys from Ebay and started programming them to my cars. My car is 06 prius with SKS smart entry, i bought one black logo FOB and another silver logo one,the black one is just like new, i have successfully programmed both to start the car but the problem was as usual with enabling the remote to lock unlock the doors, i have noticed the following. 1.when i follow the procedure described in the post,the car only lock and unlock once(may be called new mode). 2. when i press any button or both buttons followed with one button in the black logo FOB the car doesn't make any response at all. 3. when i enter the mode above with one lock unlock response, and the press the buttons on the new silver logo FOB the car quickly go nuts and do continuous lock unlock whenever i press any button on the new silver key and i cant do anything. 4.when i enter the mode and the car do the single lock unlock, and before touching the new FOB i press the lock button on the original FOB, the car perform another lock-unlock operation, and i think in this state the car is on the right mode, just like lock-unlock twice, in that state,when i try to do the right procedure to add the new silver logo FOB (hold lock and unlock buttons followed by pressing lock), the car gives me a response with double lock-unlock which means that the operation has failed, i tried the procedure hundred times with different timings, and also i tried it on another car with SKS, i had the same response, and now, at any time i do the try to register my master FOB, after holding both buttons and then press one, the light on the original fob flashes 6 times and the car preform lock-unlock once as indicator that the operation success . later....i took a look on the 06-09 prius repair manual, and i found different procedure to register FOBs(see attached file), the difference was on the times to insert the master fob in the switch and remove, i did it will and nothing happened,the car didnt do any response at all. the last problem was, some resources mentiond that the number of lock-unlock u get from the car as response is equal to times that you switch the car to IG-ON and OFF, i tried to do the cycle twice to get the lock-unlock twice but nothing happened,but..... when i did the cycle three times(IG-ON then OFF) THE CAR RESPONSE WITH TWO TIMES LOCK-UNLOCK!!!!!!! but after that when i try to program the key nothing happens, even no response from the car that the operation has failed............ any comments guys?!?!?!?!?
