Ignition key

[2000mk3]

The lock button on my ignition key doesn't always work or needs to be held down for a wile before it will work.is this a simple fix or if I bought a second hand fob is it easy to reprogramme?

Couple of things to try.
You could open it up and check that the button is working properly just using the internals.
Also putting a new battery in might help too.
If neither of those things work the new 2nd hand key is easy enough to programme, depending on what your current key has been programmed as. I.e. master or secondary.

Probably just the micro switch inside.....if you can solder its easy enough,switches are cheap from maplins etc......there are also places on ebay that refurb the fobs (replace switches and outer casing)

Is there any way of telling if my key is the master key or a secondary?

Maplin's don't have any the right size; so I special ordered a bag of 100 to dish out to fellow MR2 owners, but can't find them for the bloody life of me!

Have a search of my posts on here for other key-related fault finding, and see if that red light is coming on properly when pressing to unlock.

... It's always either the battery or the microswitch.  s:) s:)

When new I think they came with two black masters and a grey secondary.

As far a I have researched the only way you can tell is if you are not able to programme another key. Bit chicken and egg I know. If it is a secondary key though, you are likely to need to go to Mr T ad get them to set it as a Master.
For the sake of about £20 though on fleabag it's worth a shot.

Still worth checking the switch and battery out first. They are the cheaper options  :-) :-) :-)

Well I will have to try and repair it thanks for the advice

Hi what's the part no of the master key is it 1512v as I'm trying to source one of fleabay

I think the part numbers were different across the models. Look for stuff that is similar to yours. 2 button.

Yeah that's what I thought one other thing how do you open the fob mine seems to be a sealed unit

[StuC]

Little screw on the back then it prises apart

[2000mk3]

On the fob itself in side the key I mean

Some piccies of the inside of my key for you.  :-) :-) :-)
The black bit is rubbery and glued into the grey bit, so might need a little persuading!

Ok I didn't want to just force it open without knowing for sure thats how it's done thanks stu
