It's a lost cause. The A540 works with SD cards. While SDHC cards will fit into the slot, they are electronically incompatible and will not work in devices not designed for them. You need to stay with SD cards, 2GB and smaller.
it seems to be the memory card slot is damaged normally 9 contacts connect with MC if any of it doesn't contact, will not work, open and takeout card slot if the contact is bend align it to touch the MC's contacts.
There are several possible causes for "memory card locked", "memory card error", or "no memory card". The most common cause is having the tiny slide switch on the side of the card in the wrong position. The second most common is trying to use a 4GB or higher SDHC card with an older camera made before SDHC format came out. There are also other common causes if the above didn't help, with troubleshooting steps for this problem listed here.

The second most common is trying to use a 4GB or higher SDHC card with an older camera made before SDHC format came out. Please note that your particular model camera can only use up to 2GB standard SD cards. These are relatively inexpensive these days, and may be purchased on Amazon if your local store no longer carries them.

The most common is trying to use a 4GB or higher SDHC card with an older camera made before SDHC format came out. Other causes include problems with the tiny slide switch on the side of the card, or the electrical contact switch internal to the camera. The problem may also arise from simple formatting problems if the card has never been formatted in the camera (note that this will also erase the card). Troubleshooting tips for this problem may be found at this link.
You also mention recovering photos saved on the card. If you actually did take pictures with this card (assuming it's a 2GB or less standard SD card, as 4GB SDHC was not designed for your camera), you may be able to recover the photos using recovery software. See this other link.
Look at your memory card. SD cards have a slide switch along one edge. The position farthest from the contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card.
Hi! Does it work with other cards? There's a small switch on the memory card reader inside the camera which tells the camera that the card is locked. Most likely this switch is broken. You can try to point it with needle or something but I'm afraid you will have to give it away for a repair to a local repair shop or Canon service center.
