(Solved) Lonsdor K518ISE cannot be connected to any car in the vehicle list

This is tech support from for those uses with Lonsdor K518ISE failed to connect the machine to any car listed in K518ISE vehicle list.


OBD test cable testing method…here you go.


Step 1: Unplug the K518ISE main unit and turn it off


Step 2: Connect the DB25 cable(OBD cable) to k518ISE main unit, using a

multimeter and switch to the diode stalls

Pay attention that there are 3 connectors on the OBD cable:

Connector 1: connect K518ISE OBD port;

Connector 2: connect KPROG adaptor

Connector 3: connect the vehicle OBD port



Pic 1: 3 connectors on OBD cable


Step 3: Use the red pen to touch the metal part(as shown in pic 2 in red)



Pic 2: Metal part on K518ISE OBD port


Step 4: Use the black pen to test the resistance of each pin of the vehicle

connector (As shown in pic 3) , make sure that you hold the vehicle connector in the way just as the pic shows:



Pic 3: 16 pins on the vehicle OBD connector


PIN 1 and 8 should have no resistance; PIN2,3,4,5,6,7,9,10,11,12,13,14,15,16

should have resistance.

If all have no resistance, then it will be DB25 cable has problem; if the

measurement is all as it supposed to be, and the car models(those K518ISE

supported models) still can’t be connected, then you will need to send back the

DB25 cable and the main unit for Lonsdor to check(if so, let us know, and we shall talk together about the solution and details,thanks)



KD-X2 Key DIY App Tutorial for Newbies

This KeyDIY tutorial from members that have mastered the KD remote generating, kindly post a how-to’s here successfully generating and coding the remote from start to finish.



First you need to know which is the correct remote profile to generate.


Who did you buy the KEYDIY KD-X2 device through? You should also have the kd software which identifies the correct remote.

Search remote by car or remote type on kd software, select correct remote from your stock, plug it into urg machine and select the remote that was identified in kd software. Now generate remote via urg. Now you will need to add remote to car either through onboard procedure or diagnostic depending on vehicle. Not all of them are the same.

Use your wholesaler as a reference. (If that’s who you bought it through)


How do you know for sure that you’ve chosen the correct remote on the software:

look for identifying features, numbers etc.



So, this is the hyundai load key with the matching remote on kd software



also if you place original remote on urg and read remote then it will also tell you which remote to use too.
