Hi
I just replace ECU for my car because old ECU is broken.
Then I'm using Forscan 2.3.68 Licensed with Vgate Vlinker ELM327 for Forscan for programming new key.
I wait 12 minutes and to follow instruction (I've photo but can't attached because quota has been reached. I just got invitation code why I can't attach.).
I'm prepare 2 key
Turn ignition OFF and waiting 10 seconds.
Insert key1 and Turn ON then waiting 3 seconds. Then turn key1 OFF and Remove key1
Wait 5 seconds
Insert key2 and Turn ON then waiting 3 seconds. Then turn key2 OFF and Remove key2
Then insert key1 and turn ON waiting 3 seconds.
Final is click OK.
The key isn't program and my car can't start now because all the key is erased.
Please find out from my step is correct or any problem with ForScan?
Do not wait 10 seconds with the ignition OFF! The Security access will time out at 10 seconds! Once you turn the ignition off you have 10 seconds Max to get the next key in and the ignition turned back on! At the 10 second mark the 10 minuet security access will be lost and you will have to start all over again!
After The 10 minuet security wait is achieved the first key you started (Assuming you had erased all keys) with is very likely already programmed once you click "Program keys"!
It only remains then to turn the ignition off and remove the first key and insert the second key without without reaching the 10 second time out before turning the ignition back on!
When you turn that first key off to insert the second key start counting from 10-9-8 etc and make sure you have the ignition back on before you reach 1! The keys, in reality if the transponders are good, will probably program almost immediately when the ignition is turned on(Or within 3 seconds it should send and write it's signature to PATS control and receive the Vehicle signature from PATS control)!
Make sure all the keys you wish to program are within easy reach and do not drop one as, in trying to find it, will easily time out security access at 10 seconds(experience talking)!
Security access will remain active as long as the Ignition is on and the OK button is not clicked or the ignition is not turned off for more than 10 seconds or the Process is not stopped with the stop button!
If you wish to add a third key do the same thing again without clicking OK! Start the engine with the last key before you click OK and if it starts you have been successful and should be alright to click OK and exit the process!
Do not click OK until all keys desired(up to 8 in most cases) have been cycle/programmed or the PATS process will time out the security access!
About Forum attachments!
I have to remove some of my Attachments when I get the Yellow triangle, in the user control panel with the "Attachment management console" before I can get more attachments to upload! I do not know what you can do if you have no attachments in your console!
Also usually .jpeg pictures are too big for the forum server to accept so it is better to use the Windows snip and sketch(Windows Key +Shift Key+S) and capture the screen and save and attach it it as .png file which is much smaller and usually captures the whole screen with no camera interference(Lines, shadows and Cut off images) and which the forum will usually accept!
Hope that helps?
