Toyota Rav4 keyless Entry & Start not working... Fault finding and repair.

Thank you

Hi

So, to start, watch until the end... there is some interesting findings....
This Toyota Rav4 came to me due to the 2 remotes not working... and only one of them would start the car... by pressing the start button with it...
All wireless/keyless entry & start functions were completely inoperative...
Be easy on me, was the first time for me, working on one of this Rav4 keyless systems... but got there in the end...
Follow me on this video to find out what was the problem and how to resolve it.

Hope you enjoy the video.
Any questions or comments put them below.
Like always, thank you for watching!

Very well done, you would put many main dealerships to shame. Tenacity, skill and perseverance combined with thoroughly completing the job to prevent reoccurrence. Well done.

You are a lifesaver! I took my Toyota Vanguard 2010 (Stretch version of the Rav4) for angine and body power wash, and water entered that place (I didn't know). The car would not start, got stuck on the road. My first thought was something entered water in the engine. I was looking forward to a very stressful and hefty repair bill. When I bumped into this video, I fixed it myself. Just opened that same place, removed the cable connectors, and found it waterlogged. Let it dry. did all you did on yours, and just like magic, the car started, and its working fine. All thanks to you.

I had the same issue with the same type of car, toyota rav4 three days ago, but my case was with all the entry and start system working but the key does not start the car except if you touch the start button with it, after a health report generated by my launch x431, there is no dtc at all so i was by my self with that car and no help at all, i dig into the diagnostic and used that function to check the antennas, and find that the front antenna was not working, found either that i can start the car when i put the key on top of the rear seat, so i was able to realize that my front antenna is not working, i told the costumer to buy a new one or i can swap for him the antenna from the rear luggage comp to the front as a temporary fix . Thanks for sharing that

Спасибо большое за видео! Очень помогло! Мы смотрели разъемы под водительским сиденьем, но там всё было нормально. После просмотра вашего видео проверили остальные разъемы и нашли точно такие же с коррозией, как на вашем видео, но с пассажирской стороны. Всё заработало❤❤❤!!! Удачи во всех ваших делах!

Well done Luis . Logical thinking and a successful repair . For me personally one of your better uploads . I work on a bunch of cars that have been in accidents and I am used to seeing this . Not saying that yours was in an accident but water is always a point of consideration . Great job Luis .

Always fun to do some car electrics troubleshooting outside when it is raining!

Very helpful troubleshooting video. I have same Rav (US version) and had a no start condition. Thanks to you I found I had same issue with water causing corrosion in the connectors on that same junction block. Source was sunroof. Got it to run, but couldn't get any smart fob functions to work. Don't have a high end scan tool, so I had to take it to the dealer. Ended up that the BMC control module was fried. $1400 later, it's all fixed. PS, my misus moans about helping me too! :) Thanks again for capturing this.

Top fix again Luis. Good ole misty Albion and careless people keep electronics soaking wet all the time, keeping you busy 😁

Looks a bit like flood damage at some point in the vehicles life ! (And definitely leaking at the rear )Parking sensor kit has been fitted at the dealership just thrown in ( seen this before ) first class Diagnostic skills once again ...enjoyed The Video ...👍

Toyotas reputation is saved...some jiggerer has been at work on that roof rack causing the issue. And Luis drains the swamp!🤣🤣🤣

Sunday morning wake and bake is here again. Cheers for the video bro. 👍👍

Had an issue with a leak all the damage was at the front but the leak was at the back, only explanation is parking on a downward slope and water running with gravity along the roof. Confirmed with customer he parks facing down on a hill outside his house and then flat surface at work.

I love the way you go about solving the problems.

Congratulations. So with a zafira that even im608 pro could not make the remote coded and 3 other old keys also the remote part would not work. What would you do? I was thinking er? When im608 pro said hold key by receiver but never said turn ignition off first. Key in ignition but wants it held by receiver. A call to vauxhall revealed the receiver was behind drivers kick panel

This shows crearly why the cars with a lot of electronics have a lot of troubles. The manufacturers treat the inside modules like they would be inside of a house, not inside of a car. What i mean is the manufacturers should invest some money to make the connectors and modules inside the habitacle at least splash proof...

Hi, you suggested replacing the corroded pins, however i have in the past found it very difficult to buy them, where is the best place to buy just the pins?

[fatality_don]

My key is being detected but when I hold the brakes down and press the button I hear no starter sound or anything turning over and when they spark it from the front it turns over but wont turn on
