Hello fellow Buick Enthusiasts, This is my very first post on here so just take it easy on me! I have a 2005 Buick lacrosse CXL key fob that hasnt worked for a year or two. I am in the process of buying a knew key fob. My question is... Is there a newer key fob that would be compatable with my 05 key fob GM/L 22733523. Again, I am completely new to this and I am just looking to do something different.

On a different note, I am looking for some good advice on an oil to use for my Buick. I have tried everything from conventional to fully synthetic and am currently using a Valvoline Synthetic Blend.
The reason I am looking for advice is because my Lacrosse burns quite a bit of oil in between changes. With that being said... The head gasket is fine and Im not blowing smoke out the back at all. again, I have went from conventional to fully synthetic and am not at a synthetic blend "high mileage" Valvoline.

The last 3800 series I had was a 1992 Olds Delta 88. I realize that the motor in the car is great. Im just looking for a couple tips on the oil to use... If it is normal for an 05 to burn the way it has and if anyone has any suggestions on upgrading my key fab. Again this is my first post and I am new to this forum so please go easy on me. Thanks!

Super weird, but I'm brand new to here too. Years ago I owned a 1992 Olds Delta 88 and now my DD is a 2005 Lacrosse CXL that I purchased from my grandmother with 22k on it. With that being said, I have had it for a few years and I just turned over the dreaded 100k mark.
As far as the oil goes, I have tried everything from conventional, synthetic blend, and fully synthetic. I haven't read all of the other posts, but I can definitely tell you that my oil was also magically disappearing with the full synthetic as well. (Not burning, not goin out the tail pipe, no leaks, nothing detectable to me anyway) long story short, I have been running high mileage synthetic blend for the last 35k miles and I will say that it still burns (dissappears) about 1/2 qt to 3/4 qt after about 2500-3000 miles, but it def seems less to me than fully synthetic. Car runs well qmd I typically change my oil at 4k to 4.5k miles. Also, some might hate me for saying this, or blame the oil burning on this, but I will run non-synthetic Lucas through it every other oil change. Anyway, hope that helps!!

Have you tied changing the battery in the key fob? If not, take it to a dedicated lock smith and ask them to change the battery. Never, take it to a dealer.
