Lexus Startup Problems

[precious]

Hi Everyone,

I've been trawling through this site looking for a post that resembles the issue I'm experiencing with my Lexus but haven't been unable to find one...I'm hoping someone can help.

My IS 220d seems to have developed a problem with starting up - I depress the clutch and the lights come one but the engine doesn't start up. I've noticed that the problem began when I had disconnected the Battery for a couple of mins. The strange thing is, when I disconnect one of the Battery terminals for a few seconds and then replace it and then start the engine, it will start fine. When I switch the engine off and leave the car and then come back to it, I get the same problem in that the lights come on but the engine won't start.

I'm thinking could I have messed up the programming on my key fob somehow when the Battery was disconnected??...

As you can imagine, it's a pain having to disconnect the Battery each time I go somewhere so would really appreciate some help.
