    Hi, new to the forum. Has anyone here try installing an aftermarket keyless entry to their Tundra SR model (no key fob came with SR model). I did some probing with my test light that makes me think the door locks are positive triggered...can anyone confirm that? Also which 2 wires you tapped into for the lock and unlock function. If anyone has any info on this.. Thanks in advance.

    The standard keyless entry should work off of the same wires which are highlighted in the guide by @erkme73 . OP may want to check out the passive keyless entry as well too though. It's pretty legit! I put a small video and more details in my build thread here.

    Thank you both for your help. I will read the threads to get useful info. Would you happen to know if the 2020 tundras uses positive or negative triggered to unlock and lock the doors?

    How did it go? Did you find a brand that works? If so what is it? I too have a 2020 SR without factory keyless and would like to have keyless/remote start. I have been told that Vipor offers one but with limited features.

    Hi blackwaterfrog, I tried a generic aftermarket keyless entry system and that did not work. It looks like Toyota has created a complicated door lock system for the recent tundras. I was able to install a keyless entry system on a 2014 Tacoma by using a negative signal trigger to open and close the door locks. Apparently Toyota somehow change the door lock system. The 2020 tundras neither work with a negative or a positive trigger signal. If you find information on what works, please share. Sorry I don't have any good news for you.

    Here is what I found. This company (Compustar) offers many options for remote start with keyless entry for Tundra. These work with or without factory fob. There are 3 websites for 2 affiliated companies. The compustar website has a dealer locator. The customer service folks are very knowledgeable. And they offer a plug and play harness that so it won't affect Toyota warranty.

    Thanks blackwaterfrog. I will check them out for sure. I really like the idea of a plug and play harness (less chance of frying electronics due to installer's errors).

    Intermittent wiper switch is a simple swap(10 minute job max). I am looking into compustar keyless entry and remote start.

    Just did the intermittent wiper swap out. Easy fix. I can’t believe for the price of this truck they cheap out on a part that cost them a few dollars.

    ok, so any good news or updates on adding keyless entry?
    Thx in advance Brian

    I had a locksmith sell me the fob with the buttons. Programmed it and it works. No chirp sound. Just turn signals flash. I have a 2020 doubt about SR. Dealership wanted 400 for a key with buttons. Locksmith $150. Next up I’ll try adding the remote start kit from Amazon.
