I dont want to leave the doors unlocked but I want to warm up my car when im in the house, anyway of doing this with the remote

 

You pretty much have to use the mechanical key to lock/unlock the door from the outside while the car is running.

^^ that or use a brake/clutch lock

 

It's probably also worth mentioning that idling to warm up is about the worst thing you can do to a healthy engine.

to warm it up, drive it.

 

^^^ say what??? can you explain this

 

Always wanted to know it was able to lock with the car running, good question

 

isn't that ilegal in some states? to leave a car running to warm it up.

 

^^^^ i do it every morning now, because when i start my car its cold and idle at 3k for about a minute or 2, before goin to normal

 

There's been several threads explaining in considerable technical detail why it's bad for an engine to idle it to warm it up (or in general).

The owners manual explicitly states you shouldn't "warm up" the car before driving it and excessive Idling is in fact one of the things that kicks a car into the 'severe duty' maintenance schedule in the service manual and



Proper "warm up" is done by driving the vehicle.

All sitting there letting it warm does is waste fuel and contaminate your oil with condensation and blow-by from piston rings that seal poorly at idle.

Here's one of the super-long threads on the topic-

There's some 1950s-era "You should warm your car up!" BS early on page 2, but later in the page, and through the rest of the thread, you get folks who actually know WTF they're talking (Gernby, Lobuxracer, and others) about explaining why this advice hasn't been true for many many years on modern cars, and why it's actually bad to do it.

 

All I can say is WOWWWW, this is precisely why I joined CL to learn little things like this...WOW. Good to know.

 

^^^^^Totally agree
This is really good to know, I usually let my 250 sit for about thirty seconds before putting it in drive so that probably doesn't count as warming it up. I never warm up my Tahoe as I feel like the engine is so big it's warm after igniton. However... My 08 Subaru Impreza had a cold engine light, and the owners manual recommended that you waited until this light turned off before driving the car. Obviously there is the engine difference (Boxxer 4 vs. Inline 6), so would the smaller engine size make it worth it to warm the car up, or be just as bad? Don't have the Subaru anymore but just curious.

 

i still warm my engines before driving. so far no problems on my engines.

 

you meant V6? (assuming your comparing YOUR car)

 

summers around the corner

 

ok great insight, i promise i wont let it run longer than a minute. but besides that any info on locking the car while its running, maybe i want it to cool in the hot summer =)
