Need to change battery - can't open bonnet

24 posts in this topic

Hey guys,

Is there a way to open the bonnet in order to change the car battery? The battery is dead and I can't open the passenger door manaully.

A few years ago my car keys got stolen, and I changed the passenger door but the lock barrel is from another lexus.

Otherwise, I will have to smash and replace the sidescreen :(

Thanks

If you have to resort to breaking glass why not go through the rear quarter glass? - that way you can do a temporary repair and still drive the car.

That's possibly an idea, but would I be able to open the door from inside?

Because I'm imagining if I smash the drivers window I will need to lean over the door, to release the bonnet lever.

The key still opens the boot, but not the drivers door.

open the boot and remove the curtesy light assy there will be one or two wires going to it connect a battery charger to the wires or wire and charge the battery for awhile just make sure you connect the wires correctly then open with fob

Thank you guys.

I will check it out this weekday night. Otherwise it might be a next weekends task :)

I need to order a car battery charger too.

Autoglass gave me a quote over £300 to replace my side window!!!! :O

Yeah, not cheap, certainly the last resort.

It only needs a small amount of charging, just enough for the fob to open the door. You can then charge from under the bonnet once it's open.

I just opened the boot, and I assume you are referring to the small little lightbulb with a plastic cage around it?

That's it , you could put the black earth connector to another earth point to keep the charger leads apart like where the boot catch locks down

I followed what you did, and that worked.

Literally in seconds the car alarm started going off, allowing me to open the car doors.

I purchased a battery from Euro parts online, and the terminals were in the wrong position. I managed to buy another one at Halfords tonight.

Tomorrow morning, I'm going to attempt to place the lightbulb back. (I destroyed the plastic mould holding the wires)

Thanks Clifton94 and Tigerfish! :)

Never in a million years would I have thought of charging a battery through the cars wiring.

I doff my cap to you gentlemen. :thumbup:

Hahaha! That's what I was thinking all this week. It's not even April fools yet :laugh:

People were asking me, what are you doing? :wallbash:

Saved me £300 to smash my car window, and to replace it.

Now you have to find out why the battery went flat

Probably a few reasons:

  • it's 4 years old
  • I hardly drive my car (Maybe once a week 20 min journey)

I need to drive my baby more often.

My battery is in it's 10th year and like you for the last 5 years or so I only drive it once a week. When it does fail me I take it off and trickle charge it. It is a Toyota 65AH rated battery.

      Hello this is just a question out of curiosity, I've cleaned and polished my new rx300 2004 plate I've had it 2 weeks now and I believe it's running on it's original battery it looks a bit old tbf, it's a Panasonic battery and it says distributed by Toyota on it. It can't surely have lasted this long can it? Lol
      My question is which battery do you guys think would be up to the job, which brand do you recommend. Just interested in makes and models etc. Thanks

      Having a nightmare.
      Lexus IS 220d SE-I
      1) Battery died
      2) Replaced for new. COCKED UP, got the polarity wrong and fried the electrics.
      3) Checked all fuses, replaced several micro fuses and the entire fusible link. CAR 90% works, fully drivable etc however,
      PROBLEM
      Windows - The on side (passenger) front and rear windows do not work from the doors themselves or the driver's master switch, completely dead. Also the red light at the bottom of the passenger front door isn't illuminated suggesting it might not be just the windows? The wing mirrors do work however (illuminate and fold in, separate circuit??).
      Climate Controls - A separate point, the climate controls are dead, the stereo is operable from the steering wheel and the clock displays, but the main unit above with heating, air con and stereo adjustment is dead. Any ideas?

      Afternoon all
      I took delivery of my new NX three week's ago and so far I'm absolutely loving it! I just have one question for the community regrading the hybrid batteries and EV mode.
      Every time I start the car EV mode is unavailable until about 10mins into the journey. I understand they need to charge but I'm concerned the battery is not holding its charge as it should. Is this standard for a Lexus hybrid?
      It feels as though this has got progressively worse since I bought it but that could well be in my imagination.
      How does this compare to other people's experience of the NX 300h?
      Thanks

      Hello, I was wondering if anyone could  help please. I have a LS600HL and the battery went completely dead. I charged it up this weekend and the charger says it is fully charged. Upon reconnecting the horn alarm went off, but I managed to stop it. I got into the car with manual key entry. The dashboard was going crazy. The interior lights are coming on and off. There were a few minutes of very weird activity. 
      The situation now is: the battery in the boot is clicking on and off. I can't start the car. The horn is not sounding, but there is a groan/ creaking coming from under the bonnet, at a similar internal to the horn alarm. 
      The main issue seems to be the battery not providing stable power, but clicking on and off every second. I've disconnected and all is now quiet. 
      Does any one have any ideas please?
      Thanks, Rob

      Hi all, 
      Im in the process of buying(not sure) a LEXUS RX 450H SE car  - 55k miles, 2010  - 3456 cc
      But the car wont start - Dashboard blacked out
      Im guessing its the battery but not sure
      I just want to gather your opinion on how much it will cost to fix assuming it has a dead hybrid battery ?
       And list of problems that could be wrong with the car from electrical point of view - Ill assume petrol engine is ok
      Many thanks
