Need to change battery - can't open bonnet

Recommended Posts

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.

Hi I take you don't have a key for the boot 

 

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.

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.

      Hi all, 
      I have recently bought a Lexus IS300h F port and I was told to get a tracker fitted by one of my colleages. I have bought the tracker that was suggested to me but I have no idea where or how to fit it. 
      The instruction manual says to attach it to a 12-36V charger (I'm assuming the 12V battery in the boot). I have never done anything of this sort before so I just wanted to ask
      a) is it safe for me to try and fit the two leads myself?
      b) would me attaching a tracker to the 12V battery drain it & cause problems??
      Hope to hear from someone soon..

      Ps: the picture below shows the two leads that I'm supposed to connect to the battery if it makes sense to anyone

      Hello peeps. So my replacement battery i had was a Toyota Optifit which tbh im not happy with. Been 18months and its struggling as the days get colder. I bought a Ctek charger which charged it and it was ok for a day and then when i measured it across the terminals i was only getting 11.8v
      Can someone who has the original factory fitted battery take a pic for me and if they can find out the spec and part number from the battery please?
      Cheers

      Had to get a replacement battery in a hurry today for my 2003 IS 300 Sportcross, so went on-line.
      Eurocarparts website was easy to use and had a tasty discount offer. They had a choice of 2 so I selected the more expensive one with 70Ah, CCA 540A, rating and ordered it 'click and collect'. £67.40 inc vat and 3 year g'tee which I didn't think was bad.
      Now I've got it home I can see it doesn't fit the battery tray properly. The base area is too big to fit deep in the tray so it sits quite high. Also, the new battery is 10mm taller than my knackered battery. As a result, the standard battery clamp won't fit (the rods aren't long enough) and the terminals are worryingly close to the closed bonnet.
      Is this a common issue?
      Is there a work around or will I have to return it to eurocarparts?
      Is there a generally recommended/ easily available battery that fits?
      Thanks in advance for your replies!

      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?
