Tips on Duplicating Existing Keyfobs

There has always been a lot of questions regarding cloning keyfobs, as customer always ask, why we can’t clone the code successfully, even the original keyfob is a easy to clone one, such as Came Top432na, which is pretty mature to be copied in the market.

As can be concluded from previous post on how cloning remote control works, the whole point in copy is let the original’s signal cast directly into our cloning keyfob’s receiver circuit, for receiver – the most power of complete signal get would be better, so we always recommend point the original’s antenna directly to our receiver circuit in cloning remote control, since every original keyfob is different, so you may have to try several times until got a valid signal and successful clone.

There should be one different best position to each keyfob, but based on our experience, there is a common position called back-to-back copy, many customers tried and it works, but have you ever wondered why?

The reason is pretty straightforward, metal part, as we all know, blocks RF signal, so we have to make sure there is no metal blocking in the way from transmitter antenna to our receiver circuit, if your cloning remote is a all-plastic one, then back-to-back is not necessary.

Here we can take our most popular cloning keyfob SR-RCD-M1 as a example to show how this back-to-back position works, as photo below.

Best remote control duplicating position of SR-RCD-M1

The left one is for example you original remote such as Came Top432na, the right one is our cloner, as you can see, the cloner’s side is covered by metal, and there is also a metal plate in front of keyfobs, so the only side that non-metal is the back side, that’s why to put the back side straight to the original keyfob’s antenna position. and in this case, we have recorded the highest successful rate.

So every customer is advised to check out the back-to-back position if the remote cloning doesn’t work first time, and in most circumstances, problems will be solved – please note, depending on different original design, you may need to point head of original to back of cloner remote, the always same part is using our remote’s back.

As you may thought, the best way to avoid the metal problem is from design, why not using a full plastic cloner? well, that is the balanced consideration, as metallic ones is more robust and has a better look and feel in most eyes.

And what about another most popular type of casing, as used in our SR-C1 Came Top432na copy and SR-RCD-868 Hormann and Marantec 868MHz copy? yes as you guess, the basic idea is still the same, avoid metal part, an example position can be as follows.

The upper one is supposed to be the cloner, while the lower one is supposed to be your original such as Came Top432na, in this case, our original’s antenna signal is strongest in the head position, so we place the head position stick together to cloner’s back position, the successful rate has improved to nearly 100 percent sucessful cloning in 5 seconds.

Here we comes the conclusion, always place our cloner’s back to your original remote, why back – because there is no metal part there and it is closest to receiver’s antenna, and try several times to find the best position that works, you will finally get the cloner working.

If you have tried several times and it still doesn’t work, please check if it is in the compatibility list or contact us directly.
